Got a new tubing cutter, and some on sale grips. Took another 1/2" off each bar end for a total of 4" off the bars- 2" on each side. Grips are a lot firmer than the purple ones I had been trying to make work.
I'll give it a little time before I decide on these grips. If they end up being uncomfortable, I'll pull them off and just tape up to the brake levers.
