The only issues I've had with lines getting caught on anything so far has been the rudder when I have two lines out the back and stop - pretty much the same issue I would have with the revo. I'll be putting some fixed fins to alleviate this issue which Stealth sell.
I would have thought you'd have more of an issue with lines catching on your mirage fins if you are catch lines on anything.
Anyways, we'll see how version two goes...It's certainly less bulky than version 1 and a trip to weedy WP should put it to the test
