i have 2 pairs of the new px's and they suck, they release so easy when you try to 270 on or something, ive taken them to a shop so many times to get them fixed and neither one gets any better, and the din is now at 10-11 on each and i weigh 140, and i keep popping out. ive had the pivots before and never had any problems at all, they only released when they should have.
