UPDATE------------------------------------------------------------------------UPDATE
Ok, I went to the shop today because my back was hurting after morning ride. They fitted it to me doing some basic measurements and I think its gonna work now! I should have asked for a fitting first time. Lesson learned. I think the crucial thing was that my mountain bike fits great and doesn't hurt. But the seat is lower because I ride aggressive. I had a old broken ankle injury that actually made one leg shorter. Nothing I normally notice but I think the bike was fine on one leg and too long on the other causing me to rock in the saddle and hurt my lower back. The adjusted the seat forward more and also down some and I think it fixed it! We'll see on the ride home but it feels much better. Thanks for the comments.
