Yeah, that's not really what I was saying...on my rig I get some wheel slippage unless I have the rear nuts cranked way the heck down. I don't feel like I can get QR as tight as nuts...not a problem on vertical drops because there's no possibility of them sliding back and forth. I'd prefer to not use QR on any of my bikes, 'coz I've broken a couple of levers...one when cinching it down, and one when I wrecked Mtn biking. I think that they're a pain...nuts are simpler and seem more secure to me. Just my hangup, I guess.

You use QR on a fixed? Or is it SS only? Intriguing... Are they conversion wheels, or QR fixed hubs? Do you have any problems with slipping?

And to clarify-- I don't think that it's really a safety issue...for someone that knows what they're doing...or even if not, it might never cause a problem. But lots of new guys seem to have chain-tension problems, and improperly tightened QR hubs might exacerbate this (I recall a couple of 'I'm a newbie' threads popping up with questions about this.) The OP seems pretty fresh, and I was trying to limit the options to make things a little easier.

Anyway, this is pretty far afield from the OP's question; I didn't intend for it to become a rathole. Might be an interesting thread to start, though. I'm really curious how many guys use QR...honestly, I've never seen it, but I'm not really 'in the scene.' Most of my anecdotal evidence is gleaned from a a few fellow riders and the bikes I see around.
