HAHAH!
Just trying to avoid spending extra cash (beyond that I'm already sinking...) on my first build and nail down the best sizing/tolerancing as any Aerospace Engineer should...
Plus... When I was I kid, I had sweet little Hutch BMX that had an incorrect spindle length from day one. I never changed it out and it had the slightest of "clinks" on the chain stay. I'd prefer to avoid that utterly horrendous characteristic again.
