Again, at this point in time, you really should either bite the bullet and buy supershifters or settle for single speed. Unless you work VERY, VERY hard to get a drivetrain prototyped before season, you run the very high risk of not moving. There are a lot of things that you will not learn unless you go through prototyping a custom drivetrain. Currently, I think the time could be better spent to prepare for the build season in other ways(training members, stocking up, etc.).

Fair enough but there's something about understanding a design that you can get from handling it yourself. Perhaps I'm just a hands on rather than visual person. I've downloaded the supershifter design myself and taken a look. It's just not the same.
