diving,
If this thread gets out to other forums we will be trashed, but here are my thoughts. A few years ago when I was considering buying my first bike I looked all over the web and found several different way to fit a bike. After studying them and trying to make them compatible, I realised that they are not compatible and are different because the people who thought them up have different ideas about how bikes should fit. So I just make sure that I can stand over the bars comfortably and fit the bits and pieces from there. Of course I have never had a custom fitted bike built just for me. Maybe if I paid a lot of $$$ I would become a believer. Good luck with your ride.
