Neck tip: Learn to look up with your eyes, without tilting your head up. My neck sometimes gets to really hurting when biking, and then I remind myself, look up with my eyes! Keep your neck in line with your back. It takes a little practice, and with glasses, I use my bigger sunglasses as otherwise I am looking over the top of my regular glasses.

On raising bar height, I'm a big fan of one of the dirt drop style stems. Get one with the two bolt face plate.

+100 Upright bars tend to be 22.2mm, so don't count on everything moving. I'm a big fan of North Road bars for upright positioning. If you are thrifty, stem shifters work just fine, just don't get any style points. Add MTB cantilever brake levers and grips and you are done. One thing I look for at co-ops are nicer alloy North Road bars. I'm out right now. Used the last set on a build for a friend. Bar ends are always an option too. STI levers, not really......

I've never had luck with mustache bars, but I have had good luck with trekking bars.
