I am one of those fiddly fit persons as well. Back then I was not just like most riders. It is so bad now that I can barely stand to take a customer bike for a 1/2 mile test ride. As for shorts, I have become super fussy as well. Heavily padded shorts such as 10mm chamois produce too much sweat, or fabric that is "compression" fabric is too warm. Just an old fussy guy now. Smarter, too.
