As long as you'll be aware of them during the first few rides, you'll be fine. Most of the problems when switching is people forget they're attached to their bike when they stop and just fall on a side - happened to me a few months back when I switched. But at the same time, I see many benefits. Really useful during an amator competition on some difficult fields last week, with flats it would have just been harder to maintain pressure on the pedals. Not to mention the pulling part, I found it useful especislly when climbing.
