Flatlander, glad to hear you solved your problem. I had an ACL reconstruction six years ago using a hamstring tendon, and have found that I absolutely HAVE to do the weight workouts for the quads and hamstrings, even after all this time. Like you, running has never bothered me, but cycling sure did point out that that hamstring was not and probably never will be as strong as the other one, since the tendon is being used elsewhere. No matter what they say, it ain't the same as originial equiqment! Anyway, I just wanted to let you know that you are not alone.
