I borrowed a 10 for an afternoon a couple of weeks ago. I have flown a few different sizes in both 06 and 07 Waroos and the 07 Waroo pro. Initial impression was that the Bularoo was even more stable in the air and I really enjoyed using it. Others that I know who have tried it at our local spot also were positive. Build quality looks really good, reinforced everywhere. I would probably purchase one over a Waroo, but hey... wouldn't trade my Rebels for one

PS. saw someone boost HUMONGOUS jumps with it last Sunday.
