Jim I know not all shoulder surgeries are the same but I had mine done this past March. They trimmed up the frayed rotator cuff, took out all the bone spurs, and repaired a full thickness labrum tear. Surgery was March 5th, to the dismay of my therapist I was riding locally in early May. I went on a Saddlesore run May 17th covering 1100 miles in 18.5 hours, and went on a 2200 mile round trip up to Niagara, met you at Bob's, down to Don's, and back to KY in June. The shoulder felt better on the bike than in any of our cages. It's pretty accurate on the weather forecast but I'm glad I had it done. I had gotten to the point of not being able to work between the weakness and the pain. I will suggest you have a good recliner, it was the only place I could sleep for a few weeks. After that I had a chair by the bed, I'd prop my arm in a pillow there to sleep. Good luck.
