Sounds like we're both about the same size and weight so maybe what I've found successful will be of value to you. BTW, I also have lower back trouble that I have to be careful about. Unfortunately, my solution will not be cheap. I have the Ultimate Mid Rider with rider backrest, HeliBars, and Madstad. With this combination, I can totally dial it in and ride in total comfort all day long. To be honest, I don't believe it gets any better than this. Like someone mentioned, the Mid Rider does move you forward just a bit but with my 33" sleeve length, I found that to be a good thing. Of course, the HeliBars are adjusted back toward me to get it perfect. With this setup, I am finally done messing around with seats, bars, and windscreens. Of course, there's still a lot of other things I can mess with
