I have 3 words for you and you don't want to hear them...flex ski + doolys. I've been thru 4 different ski combinations (and I'm tired of buying/selling skis). This is the ski nirvana I've been looking for. Quick rundown in the order I tried them:
precisions-well you know
usi vx301 6" shaper carbide-good corner bite, very little darting, very high steering effort
flex ski with pcs strips 10" carbide-decent corner bite, little less than usis, little darting, reasonable steering effort
powder pros 9.5" carbide- very agressive corner bite, these will never washout on ya, quite a bit of darting and high steer effort
flex ski, removed pcs strips, 8" doolys- good bite in corners, almost no darting, least steering effort of all
Couple other notes, I took the time to set up for every one when I changed skis, varying spring preloads, limiter straps, etc. My toe out is 1/4" total, haven't changed that.
On the PP, I took the time also to shim the front of the ski up to try to kill the nervousness, no dice.
The flex skis without the pcs had excellent bite in the corners and steered real easy also, but darted all over the place, nearly unrideable.
Downside of the flex skis is they have zero floation in powder. The PP were excellent for that, usi somewhere between the 2.
My sled is an 04 renegade 8oo. I hope this helps somebody, I know I've spent a lot of time and money f'in around with it. Good luck.
