What I have done on my Bombadil, and like a lot, is to put the brakes
at about the middle of the straight section. I then use cork tape on
either side of each lever (4 sections for the whole bar). Hands go
most anyplace. Outside the levers, on the levers, inside the levers,
all good. Since the clamps for my levers are thicker outboard than
inboard, ometime I may try doing one layer of cork outside the levers,
then start a second layer at the end of the bar and run it all the way
to the strut just going around the lever clamp sort of like you do
with road levers.
I have paul thumbies mounted on the arc right next to the struts and
have not bothered to tape the arc part of the bar.
If I were doing a single speed I think I would run the tape right
across the strut junction and end both sides in the middle. Might even
tie a monkey fist over the twined ends in the middle like marking the
wheel of a boat.
