3) the shift happens in transition, are you saying that you don't have a transition phase? plus if you stay centered on your skis you really don't have to move that much. on the other hand if you are riding the back seat...
4) that makes no sense. I have no idea what you are talking about. But I do know that in transition you have to unweight the skis, you can either retract your legs and stay in the tunnel, or extend them.
5) What???stay on the ground as opposed to what? floating in the air if you stay forward?
6) learn biomechanics
7) why would you want that? and again shorter edge --> less bite
1) shorter edge = more pressure per inch of edge in the snow. If I was to ask you if two ski edges could grip better than one ski edge (such as the inside downhill edge only vs. edging both skis equally) I'm sure you would tell me that one edge works better than two edges at gripping the snow. However, that cuts the edge length in two. So which is it? More pressure on a shorter length of edge or less pressure on a longer length of edge that grips best? You can't have it both ways. It's clear that you don't understand the concept of pressure in relation to the snow. I tried to explain it before but apparently you don't get/don't want to. Anyway if you had understood it you would have said that I would say 2 skis hold better than one. In fact you never ski 100% on the downhill ski but rather 60-40% (it changes with snow conditions, let's see if you can tell me why?) Where is and when was the explanation you write about above? I think I agree with you on this one, but most of the stuff I've read seems to be promoting the benefits of switching weight 100% back and forth between inside edges. I've been advocating using both skis for a long time, sometime even mostly using the outside edges. I wouldn't want to put a percentage on it because the ratio varies according to the needs of the moment. The 100% inside edges dogma just seemed to leave one with one ski dangling around that you still need to keep pointed in the right direction so you could make the switch for the next turn. I say better to edge and pressure it much like the other ski so they ski the same and stay lined up with each other that way. One argument I read was that the single ski could be pressured harder in the snow and would grip better than two would. I really don't know the answer to that one. Another one was that you could bend a single ski more into and arc and it would therefore carve better. I guess I am heavy enough and use my skis hard enough I didn't have much trouble bending both my skis into an arc to carve them. The main reason I liked using both skis was that then you have the strength of both legs to help you absorb the tremendous shock when checking hard in the moguls trying to control your speed.
2) Is based on my own experience in this regard, not on my ideas. Yes, same problem different words. It's what you, and only you think. (are you going to argue that your experiences don't influence your ideas?)
3)The transition is lightning fast, all that has to happen is for my knees to go up some as I cross over. It's not a big movement if you remain centered, I've already said it. Raising your entire body is far more work than just letting the virtual hump raise your knees.
4)The knees come up but the tails can still be pressured some by levering back on the boot. I don't really unweight much, I just roll my foot over to the other edge while it still has some pressure on it. That is one of the reasons I like very narrow waisted skis (in the low 60mm range). That's the only reason why you can probably ski like the way you say you can...No but I choose to use them because they are easier and quicker (and as long as they are shaped they still work reaonably well in the pow By the time the width gets much over 70mm on the ski's width changing edges this way takes noticeably more work to lever my weight off the snow (as the wider ski tilts my boot up higher becaause the weighted edges lever my weight higher in order to edge the skis. Also unweighting is not as quick because of the time taken for unweighting and reweighting the skis and the addition effort used to lift the body up higher (because of the greater time gravity has to lower my CG if I was (down) unweighting. Please don't try to make up physics to support your ideas, it doesn't make you look good...You are going to have to be more specific to get a dullard like me to understand where hes wrong. If I took the time to unweight the skis, there wouldn't be this extra effort with wider skis due to edging, but the edge change would take even longer with wider skis and so I'd have to jack my CG up higher again to recover the distance it fell during the longer time down unweighting. Up unweighting would be far slower still and require even more effort.[I should work on this more to make it clearer, but I'm very sleepy and want to go to bed.] Please take you time and re word it beacuse like that it's very had to follow. Unweighting would eliminate the leverage due to the wider ski being put on edge but would take longer. Down unweighting would be quicker than upunweighting but I'd have to lift my CG more again afterwards (equal to the distance it went down during the time I was unweighted). that used to happen when I made multiple fast turns. Id sink lower and lower. I seemed to have since overcome that or at least decreased it a lot in the last few seasons.. I think that is because I'm no longer fully unweighting the skis in the cross-over.
5)No, as opposed to floating in the air when they are unweighted. If you stayed forward the tails would wash out and you would have to then skid them to a stop with a hard edge set (build a platform) before they could again start carving. More time wasted. Tails wash out when you rotate your upper body with the skis and don't counter (javelin turns). Tails wash out when they don't grip the snow as well. There are numerous reasons why that might occur, not just lack of counter.
6)What is wrong with what I said? Don't you think I can get the most edge angle on the skis with the least effort this way? What's wrong is that you don't know biomechanics. No, look at Ligety he doesn't keep his edges on the ground all the time and yet get greater angles than anybody will ever get. Why? the secret is somewhere else...What specifically do I not know about biomechanics? I'll bet Ted would keep his skis on the ground all the time if he could. Skis are easier to control when they have something to edge against.
7)So they don't need to be re-bent to carve around their arc if I can keep them bent during the transition. (and same question as for #1 regarding "less bite") Skis will bend in function of angle and pressure, the bend on your tails is different than the bent generated on the snow Huh? are you saying that the skis bend because the shape of the ski and the angle and the pressure on them determine that. That's true if you are using the whole ski but I'm mostly just bending the ski's tails and edging them into the snow but that bend is still because of the pressure on them against the snow. ????
