Religion is a brilliant kite. In decent winds (ie today WA 30knts) it will not only drift backwards on waves as much as you want, but you can almost fly it backwards quite quickly and steer it as it goes. Perfect in waves.
Only downside is the pulleys: I've had plenty of pulley blowouts (from what i've heard not many people do though) and snapped bridles from chaffing and now run stainless rings (still Chaffe through the bridles fairly regularly). Minor detail though and I would definitely not let this put you off. I would (and will) definitely buy another one without hesitation.

Haven't flown the reo, but would be keen to for the comparison - heard good things also. I can't sufficiently describe how much I love the religion though. Absolutely buzzing still after today's session!

awesome!
