OK. So here is what I'm skiing:
- Skis... Rossi Experience 88, 186cm. Skied them about 30x last year. Love the skis.
- Boots... Dodge Boots, 315cm. Custom footbed. Neutral stance.
I'm not normally a backseat skier. However, I found myself skiing backseat a lot last weekend and having difficulty carving my turns. Now, the conditions were as bad as you could possibly imagine for this time of year. Essentially just rockhard ice with a week bit of snow on top. Still, I've skied really bad conditions before and skied them well.
I'm going to go to my bootfitter and tell him the problem and hope that he can correct it. I love my boots. When I got them in January they literally helped boost my skiing ability by an appreciable measure. So I don't think it's the boot. I'm thinking it maybe me but I'll see what the bootfitter says.
Glad to hear that your 2nd day of skiing was MUCH better than your first. But the fact that you're quads were "KILLING" you, still leads me to believe there is a significant error in your net ski/binding/boot stance.
If you review my original questions and your answers above, you'll realize that you omitted a VERY important piece of equipment info, namely, what exact BINDING model are you skiing on? The reason this is important is because of varying differences between binding toe and heel heights, often referred to as the "delta" or "ramp" effect of your binding. In essence, how much the binding is tilting your entire boot forward (or backward), relative to the running surface of your Rossi ski.
Since accurately identifying a binding model with all parts can be difficult for the average skier (beyond brand and whatever name or numbers you can read), I'd like to suggest that you take some up-close photos (top, side and perspective views) of your toe unit, heel unit and overall toe and heel set up. The closer the better, including a clear shot of your toe and/or heel tension setting windows. If you shoot and post these at your convenience, I'll be able to identify the "ramp" effect of your binding and how close that is to what others are choosing with your given boot model and size. It would also be helpful if you're willing to share a couple front, side and rear shot views of your feet and lower legs from the knee down, standing on a hard, flat surface. At the very least, you may become famous on Epicski for posting such photos!
Another thing you didn't mention was whether you were able to visit your boot fitter as planned and if so, did he make any adjustments between your 1st and 2nd day of skiing?
At least know, the more you're willing to share, the more some of us are in a position to help.
