I've been subluxing anteriorly for the past two years and just had arthroscopic surgery (labral repair - the tear was 6-1)5 months ago. Since I had repeated anterior subluxations my experience may be different than yours, but the surgery would be similar.
My boating hit a plateau for the two years when these subluxations were happening since there was always a possibility my shoulder might pop out in the middle of a rapid rendering me useless. It happened quite often playboating (flatwheels) but only once creeking, and that was the tipping point. Finally it got to the point where if I put my shoulder in a compromising position while sleeping it would pop out.
When I get around to it I'll post some info on my website about my experience with the surgery and follow up. Long story short the surgery was the best choice I could have made and I wish I did it a little earlier. Not only will it prevent arthritis later on (if you wait too long it is possible to wear down the ball part of the shoulder joint so much that a bone graft is necessary - unlikely but possible), but you regain confidence in sports where having proper shoulder function is critical.
5 months out I'm running fine, have done some easy kayaking, am back on the bike, and really just need to do more weight training to strengthen my shoulder muscles again. Feels better than my other shoulder.
Let me know if you have any specific questions.
