From my experiance the ITP's suck. I run the lumber jack 7 paddle with the smoothies up front, my brother got a rhino about the same time I did and some idoit talked my brother into buying the ITP's.
Our first trip we where both stock and we went over to test hill at gordons and made a few runs, I made it up the hill every time and he could not make it up at all. He tried different air pressure with no change, he thought mabey it was his rhino so when we got back to camp we swapped paddles and made a run back to the hill. This time he made it up every time with my lumber jacks and I coulndt make it up at all with the ITPs.
As soon as we got home he pawned them off on some one else.
