I've always been lucky with chainlines. "Oh, cool, that worked." Or else I just don't get into it unles I have a problem, and haven't had any problems. I'm still on the QB's original BB.
I've also happily run fixed for years and years without lockrings, but I may have been lucky there, too. I use the Chaingang Rotafixa method of binding the chain on the bottom bracket shell and using the back wheel as a lever to mount the cog or crack it loose. I just started riding the Quickbeam with a freewheel, which is fun, and different. I've had to resist the temptation to flip back to fixed, though, since I want to really give it a good try. I would like a WI double FW, but so far the 17t is working fine. 36/44 x 17 freewheel 36/44 x 17/21 fixed.
