Got a fit with my 110mm stem. Was told that I was on the VERY edge of fitting that stem and if I decided to replace it to get a 100mm or 90mm stem. Felt too stretched out and had lower back pain on longer rides.

Jumped to the 90mm stem, same degree of angle and it was much better. It was a big jump, but worked out. Cannot stress enough the importance of a fitting. I may not have changed anything and tried to suffer through it. Doesn't cost that much and the return on investment is feeling great on your sled...
