I never said they didn't work, I still have mine today. They have gotten me through every big rapid on the Deschutes, save Oak Springs, but they tear up your hands if you are rowing fisherman all day. So it depends on what you are actually doing with them, because if you are just rafting and your oar strokes are limited to keeping you in the middle of the river, you will be fine. Although, if you are trying to fish people out of the boat, and you are contantly trying to slow the boat down and put it 25' from the bank, your hands will feel it (especially on high gradient rivers). Just my experience. As far as the SDP being overloaded, I was just trying to interpret.....I have never owned that boat, only riden in one.
