I am starting to wonder if there are no sling guys currently active on HW. Otherwise someone should have answered by now.
You have heard all my stuff but as I think more about where you are I still reflect on my past and say that I am glad I tried the sling even thought it did not work for me. Only down side is six weeks or so of recovery and the possibility of two operations. If you and/or your insurance don't mind the sling is always worth a try...my opinion. At least this will bump this thread up again in case a sling guy is listening.
