I am looking to purchase a small raft for smaller volume technical runs. Does anyone have any suggestions? Diminishing Tubes, shape, size, material, brand? I have been in an 11.5' Sotar SS on the Lochsa, been in an older Aire Puma and 12.5' New Wave 1 Maravia. I like them all, but overall I have to say the Sotar is my favorite. I would be using this as a paddle crew R2 up to 5 on rivers such as the Lochsa, SF Payette (Staircase and Canyon runs), Yaak, White Sands, White Salmon...
