I've said it before and I'll say it again! Don't fuck around, don't get no-cuts, get Woodcraft!
I lowsided in T1 at JGP on my GSXR and the slider saved my bike. I lost the front at over 100mph and the bike was fine! I lowsided on the street going about 20mph and not only did my "no-cut" break, but before it broke the mount rotated around and cracked my fairings from the inside! It completely fucked up my fairings.
They're specially designed, two-part sliders, with replacebale pucks. The pucks cost $15, so if you go down, instead of replacing the entire set-up, all you have to replace is the puck. Plus the design is such that it's a LOT stronger than most and it's very easy to replace. The owner of woodcraft is a professional racer, and thought that most of the stuff out there was crap, so he started his own company and made his own parts. Check them out:
