I've had Full Flight's +2s (off Ebay even) on my Banshee for the past 2 years. Wheelie landings, jumping, even take em to the woods once in a while. No real issues to report.
I did wear one of the aluminum bushings about 6 months in...pinged Full Flight to ask them about it, they sent me a whole new set right away, free of charge, no questions asked. Customer Service seems to be great with my one need for it.
A little maintenance keeps the squeaks and rattles away.
