[ERA Chas]

DLang,
Consider the ERA rear suspension option and a Richmond 5-speed. The ERA rear is 50 lbs. lighter than Jag, fully adjustable for track use and a much easier brake bleed [outboard vs. inboard] The Richmond takes big power and allows a higher R/P ratio. It's only $$$.
A 28 yr.-old nymph might make the build "significantly easier".
Good luck, especially with Peter-the-hero-eater.
