Thanks for the replies guys. I ended up buying a Jagwire Racing kit, and think I will use my Dremel to cut them as I just can't stomach another $30-40 one-off specific tool.
I think I'm going to be a bit dissapointed with mechanical brakes after the hydraulics, but I just can't stand flat bars on the road. This is turning out to be a lot more expensive an endeavour than I first anticipated. Between the Avid BB7 Roads, Easton EA30 Aero bars, Jagwire cables and STI shifters, I'm for about $330, and I haven't even considered bar tape yet.
That said, I'm pretty jacked to get my 'new bike' together!
