Honestly neither - I have them on my '03 Summit and had to put shaper bars on them just to keep from pushing so much and they don't float up in pow good at all. The newer mtn pilots are "acceptable". The best mountain ski by far are Mods (and yes, I have tried powder pros and simmons too): http://www.modsskis.com/
