Indeed. Nice job on those.

I always needed to use glue or shellac to keep twined termination from loosening up over time.

Partly I like 70s top down style because I prefer the look of no termination at the top. Also it holds up slightly better for me. I think I tend to pull back on the bars slightly when climbing, so the whole shingle analogy is bassackwards.

Figures. At any rate if you look at old race pictures, say from the 70s, you'll see that most bikes are cotton tape, wrapped top down. A few, notably Eddy Merckx, were wrapped bottom up. It could be argued that there was never a right way, but IMO it would be more accurate to say that Eddy wrapped his the wrong way, because he preferred it. Eventually that became the 'correct' way.
