I’ve got a KH24 GUni and cut my KH touring bar almost identically. While I’ve only had a few chances to test the setup out, I will say that so far it has really helped with riding in high-gear overall. The good thing about the KH touring bar is that it is so customizable that you’ve got a good chance at dialing it in just the way you want. Beware that with the bar cut down as far as it is, you may need to cut the “T” section to be a bit narrower as you’ll hit it with your knees (happened to me).
Good luck!
