help me understand sidecut
I have recently bought a new pair of skis with my largest sidecut to date. I understand a few things about sidecut but I am trying to put it all together and need some input. I have searched and read chupa's post about sidecut to length ratio but it did not fit my needs. Here is what I know,
1 the less sidecut the bigger the turn edged turn
2 the less sidecut the more stable at speed
3 running length affects the arc of the turn as well.
here is what i would like to know. the shorter the running length the quicker the turn in relation to the same radius with a longer running length? stiffer ski will hold you on edge firmer? in genreal, I need you guys to tell me what i am missing, I am having a hard time phrasing the question.
I am going from rossi bandit xxx 195's 30* radius i think
also have b3's in 195
and jah loves 30* radius
the new ski is 191cm 35mm back tip rocker(kinked) so it is a short rise early rise tail
146-128-133 turn radius 40m i dont know the running length but it looks short, super stiff in the running length, soft tail and 1/2 the tip
some of you know what ski this is, and specifics would be great but i am looking for an in general responce.

Why don't you check out this review and see if you can get a feel for an answer to the question you don't really know. Or help you frame it better/at all.Nine out of ten Jeremy's prefer a warm jacket to a warm day

Don't take turn radius too seriously. Any ski will make any radius carved turn if you know what your doing. What more sidecdut does is let you make a tighter turn with less tipping of the ski which means you can make a tighter carved turn at a slower speed. Same thing applies to softer vs stiffer--it's the bend (reverse camber) that allows the ski to carve--the softer the ski the less speed needed to bend it. As far as length vs radius--many ski manufacturers will give a longer turn radius for the longer ski in a given model. So the shorter ski in a given model will make a little tighter turn than the longer. And stiffer means better edge hold. But my son can take his old soft park skis down steep ice a lot better than I can on my stiff skis. It ain't the ski, and I'm sorry but this stuff belongs on Epic.

Sidecut can be measured in turn radius. A large turn radius (ie 40 metres) = a small sidecut. A short ie 165 ski with 15m turn radius will carve a turn like a 190 ski with a 15m turn radius - although the longer ski will feel more stable at speed. A small sidectu/large turn radius means the ski won't turn very quickly, and so will feel more stbale in a straight line or big gs carve turns. A totionally (so sidewyas across the ski) ski will have better egde grip.

seriously, I prefer TGR. I know most of you are advanced skiers who know alot of this, but I ask because I KNOW you know, so I'll take that. alot of the responces are making sense. Time will tell.Falling feels like flying........for a little while.
