lets look at the messengers and see what they say...A LOT of them *here* use clipless...a lot don't. i have heard of eggbeaters breaking. **** happens. I personally use g9-9s...f'n comfy as hell. probably going to go clipless or powergrips before too long. always bending/breaking cages...broken straps, too. and seriously, how many people actually adjust their straps often? i never touch mine, until they get too loose, then adjust them again when i overtighten them...when it's all said and done, get the gr-9's. the sylvans aren't very comfortable.
