Yeah, it's not going to turn like a canoe with more rocker. And we all know there are varying degrees of class 2.
But I also take into account my style of river running in most cl2 uses more sideslips and backferries than quick turns. (BTW, part of my test was paddling in reverse, which it did perfectly) I wouldn't hesitate to take it down any cl2 I've ran with a weeks worth of lightweight tripping gear and food. Its depth might even make it a drier ride than the Wildfire sometimes.
I'm not sure it's fair to compare it negatively to a 16' Prospector paddled solo with a load in technical cl2 rapids. BTDT, and frankly, it's easier standing with a pole. Leverage advantage makes up for a lot, and taking a foot off of each end of the boat does make a difference in turning. I've been pleasantly surprised by what I can get away with in that regard when paddling the zero rocker Solo 14 in cl2.
Everything is a compromise, and I think that Prospector 14 is a great all-around for anyone willing to compromise on what rapids might be run and what might be avoided. I admit though that if I could have a modern composite version of my old MR Guide, I'd probably choose that for rivers over just about anything. What a fun boat! (I probably should be looking for a Blue Steel Supernova - specs look so similar.)
