Nice - just fill her till she's firm. My tube is a North X Northwest V-boat. Like it more than the two Caddis U-boats i had before. One of these days I'm going to have to break down and get a toon instead of the tube. Had a heck of a time last summer after going a bit too far on leg power out at Hagg, on a windy day. Gunga (youngfishtyler) and I were out cruising for bass, and we went from Ramp A down to the dam and back, and the wind kicked up a bit. Got pretty tiring kicking all that way. Gunga was using a borrowed toon with fins (heh, no oars available I guess) and he was making no head way. I was doing better - but about 2/3 the way back, I had to beach myself and carry the tube back along the beach, I just couldn't make much headway against the wind after tiring myself out. I think a toon, with oars would've been better.
Even better would be a toon with a trolling motor...
