Disagree with the detuning straight skis = rocker assertion. Rocker is most definitely an advantage in heavy snow. Remember "sit back"?
Really, if I posted that in a gear forum that people with those skis actually read, the flame throwers would be out in force! That's why I didn't quote you to protect you from...well...maybe a one-click flaming anyway. No ski with a rocker of course needs to be tuned apparently

You mean 90 km/h ? or 90 degrees?
Well, we know they go straight pretty well...

The last pair of straight-era SL skis I had were 200cm TR4s. These were run with a flat base and a 2 degree edge angle. Again, detuning was only done on the parts of the shovel & tail that were outside the contact surface.
Even back with straight skis, detuning, although very common, was not universal. Leaving the full edge sharp gave a good performance boost, as long as you paid attention to lateral balance.
Ah...forgot to ask about the base bevel! I'll probably run them flat also or maybe a half. Few shops can actually get a flat base anyway.
I knew the SkiVisions planer thing would come out! Well, if I had that Ruby stone I might consider it, but the stoneI have isn't worth much even in the garden for the snails.
Plus, I'd love to see the guys face when I bring in the P20's for a stone grind. I think I'll go to the guy who's got the automatic one with the vaccuum hold downs for the skis, and the Lcd readout.

So for a 200 cm I would detune 30 cm of the tip starting just before it flattens out to touch the snow and then 20 cm from the tail up the same way.
30 cm of detuning! Good god man! That's quite the rocker you've got on those boys.
You ski them all the time right?
Question: Why not just ski a shorter ski?
