M730 cranks were still in the lineup in 1993, which is RC200 times.
I am currently going through the same dilemma for my 93 Lotus build. M900 is what I would like but good stuff goes for so much these days. Even M730 seems to be going up in price.
On your Pace though, I like the M730/5 sort of idea, then obeying the laws of pace, adding a M'burn crankset.
