I did see a version this w/e with the loop at the top, but instead of the loop itself going over the top of the valve a double loop was made by threading it through itself. Very simple to look at, but hard to describe :) This seems to have the advantages that 1) there was no knot at the top near the valve and b) the size of the valve was irrelavent. I couldn't think of any disadvantages... r Paul > > Yes, both tapes need to be viewed - the second attempted to address > issues not clear in the first, but both are packed with info. > > > Jim Cobb wrote: > > > > Thanks for the clarification, George.
