If I was wanting to see what angle was best for me, but knew what reach, I'd buy the cheapest adjustable and figure what angle I wanted, then buy a regular stem. I want something solid when it comes to steering. IF I was to use an adjustable (but don't think I would), from what I've read, the only one I might consider would be one from Ritchey: https://www.jensonusa.com/Ritchey-4-...20Group%20%231 The two bolt design for adjustment would seem to be much better than a single bolt.
