I friction shift using Paul Thumbies on the bar tops, as that's where I am most of the time anyway. Note that this makes the handlebar real estate very tight. I had an arkel medium bag, the thumbies, cross brakes, a computer, and my iphone 6 (quadlock). No room for a light, so right now I've removed the handlebar bag and am using an Ortlieb trunk bag. Not quite as convenient, but close.
