Re: safe tubing
if you don't find/use a quick release(i haven't seen them), i'd still tie to the tube. even if its an old truck tube (the kind i used to ride). it would be very hard to physically keep the tube under you while holding the rope, because the tubes 'catch' in the water alot and you'd end up skimming water on your belly quite often. i have bought a tube made for pulling, just haven't tried it yet. the tire tubes would chaff you if you didn't have lots of oil on. to keep the rope from getting too tight on the tube, we'd use a bowline knot that doesn't shrink the loop.<br />-just my opinion on tubin memories-
