Fly at practice in narrow lanes?

I don't do fly though I wish I could (at least enough to make it through a 100 fly or 200IM). I'm switching to a different team this year, going from Northwestern's nice wide lanes to the much narrower lanes at the local YWCA. Now I think I will wind up doing even less fly. One of my problems with fly (even at NU's pool) is banging my arms on the lane lines when circle swimming. That really does a number on my shoulder. Now I'm all but guaranteed to whack the lane line. What's a poor fella to do? Skip
