Paddleboy17, you present a logical position and make much sense. My experience as a tourist, race boy, then tourist again is one of frustration until I was fitted by a master fitter. Have been riding since the early 70's and throughout the entire time my upper back and knees had always given me major issues. Used every method of self-service fitting available (Lemond, shop employees eyes and knowledge, European shop pro fit in the 80's, and even followed a mathematical formula found in the Paterek Manual) with no solution. When fitted 4 years ago by a competent shop the problems disappeared. Come to find out the saddle I used made a big difference in my upper body's attitude on the bike. Along with that, it was discovered stock frames have too steep seat tubes for me, although proportionally I am very average for 6 foot tall. I ride an odd ball custom built frame with 72.5 seat angle, 59 cm seat tube, 56 top tube, and 71 head tube. Fits like a glove and after 5-6 hours in the saddle I feel just fine!
As a young college racer boy, no way could I have justified the expense of a 200 dollar fitting if it had been available then, but now I know better and will preach it to the world! It has kept me on the bike. BTW, bents have their own issues, of which fit can be one.
