I have a 2007 Hyper type and am a newbie

Have tried the Ozone sport as well, imo the ozone is the one to get, all other things being equal. From my experience the RRD does tend to luff a bit, not a problem if you're watching it but I have had a couple of close calls when really inexperienced. The Ozone I had lessons on was really nice, no luffing probs at all

Had the RRD out today at Leighton, and it did try to luff once but as I know its gnarly tricks it wasn't a problem

It's not a big issue though, only happens once or twice a session if you're not paying attention and you can still catch it.
