I'd say, for me, no. I had the in store custom Guru sizer fitting and while I love the feel of my custom titanium bike, I still have all of the back, neck, and other issues I had before. Like you, I stretch, gone to PT on and off for 5 years, blah, blah. The only time this stuff stops is when I don't do any exercise, so since that is not happening, I continue. I wouldn't necessarily discourage you, but if I was going to do it again, I'd go to a PT fitter, like Wahine.
