Mike's comment, "They used what worked," echoes thoughts I've had about this "hobby". I guess I'm trying to get back to that "zen mind-begginers mind" state like when I first got into bikes in the 70's. (ok...we did do a few dumb things....but that's how you learn.)
My new mantra, rather than "Period Correct": "Correct, Period".
