I'm not a hard core creeker but I do enjoy class IV+ rivers and creeks. I've had the Mamba on the E-P run on the Yuba @ 1200 cfs, Lower Tuolumne @ 1200 cfs. The Meced @1250 cfs.Miracle to Democrat on the Kern, Arroyo Seco @380 cfs as well as a few class III runs (including the S.F. of the American @7,000cfs) Before buying the Mamba 8.0 I tried the Diesel 6.5, Prijon Cross, LL Lil Joe, H-3 and Jackson Hero. All of these boats have some strong points but for me the Mamba was best overall. The Mamba is very stable. It is very easy to roll (So easy that my roll got sloppy and I've spent some pool time with my play boat). It doesn't spin as fast as a highly rockered creeker but it does have enough chine that it responds well with some edge control. The chines are softer than the H-3 so it doesn't carve quite as well but they also are less suseptable to catching on rocks. Stern does not seem to be suseptable to grabby hydrolics. When it has been grabbed it...
