I've been thinking about getting a smaller raft for doing low water tech runs down the Middle fork and Selway rivers. It seems that high water years are going the way of the buffalo and this might be a good way to extend my season. I've been looking at the Aire 13D, 13E, and the Puma series. I have been watching some videos of Jon Barker doing low water Bruneau and Owyhee with the 13E and it looks very capable. The added .5" on the tubes on the E series could be nice to have in low water, but the D have a smaller waterline albeit slightly smaller tubes. I have rowed a superpuma down the MFS top end @500cfs before and it was a breeze. I remember wishing that it was a little more stable for some of the bigger drops, but it was pretty sweet. But I would like to put on a little more gear for multi day. The super duper looks nice but the long waterline has me wondering if it would be difficult to spin and turn on a dime.
