okay, i have a pair of marzocchi z3 qr20's. lately i have been noticing that they kinda stick, i can shake the bike around and the forks wont contract, but when i go off a curb or something they work just fine, its like they are super stiff, but when i start jumping around they unstick and feel like they are the way they are suposed to. i dont remember them doing that when i got em, they also have no play back and forth (like a worn out pair of forks are suposed to). i wore out a pair of rock shocks and they wobbled back and forth like crazy and felt like i was on a flat tire or something fully pumped, maybe it a marzocchi thing only
