I've been flying the 14xl's for 3 years. Not the comp model, so can't speak to that one, but the regular acro's are a pain. Unless you have fairly easy access to repair facilities, I'd stay away from them. Rotors are the main problem, I've had them last from 80 flights to 180 flights. They'll start drawing huge amounts of amps if not caught, so you have to keep a close eye on the amp draw or you'll end up smoking your esc, even the 90 amp models. I'm in the process of switching over to the outrunners, they seem to be less worrisome.

Haven't flown the 22s, but put about 50 flights on the 20s. Nice motor and ran great with a 19x10 prop, but wasn't quite what I wanted, a light plane will help. The A60's you can only front mount, you'll need a mount or a strong nose section. The 22s should be able to swing a larger prop, might be worth checking out, though I've never seen one fly.
