Tressostar is kind of short for me so I need a little more that two rolls. Newbaums is long enough that two rolls suffices, but with not much left over. I wrap from the top down and from the bottom up and meet, of course, at the brake lever. So I guess that puts me between 17.4 and 20 feet according to Reynolds 531 post. The past two times I wrapped my bars, I shellacked them and I like that.
