I have not used them on my own sled. daveyboy/dave50 on here has them on his sled and I have used the 5.5 ones on my friends xp. On the xp they work great untill you get to a place where the trail is crusty, then you are riding a really light sled with skis that are yanking your light sled around even easier than the heavy sleds.
Daves sled handled very good with them, he has tripple points on them, still I felt they worked better than the others I tried but again, two different sleds, two different skis.
I will probly bolt some dartless under my friends xp skis this winter when he isn't looking and see what he has to say.
I do like the look of the pilots, I dont like that they are skidoo skis. Its bad enough that you had to put on skis but really, skidoo skis!!!!!
the skidoo skis are still after the hype, a ski that will act like all other single carbide ski when the conditions get crusty. Like all other single carbide skis, to overcome this, they need add ons like dual carbides, dartless, cobraheads, easy stears, snow trackers, etccc. Even the magic ski company finally admitted their ski darts and sells a fix for it that copies the dartless, slp plates and snow trackers style of fix.
