After the work, I made it through four 20 minute sessions with just two misshifts. I'm still not loving Lotus's shifter, but it's better after his mods.
I had the same problem, put in stiffer transmission mounts, and the problem is gone. (Down side is that there's more vibration conducted to the driver, but it's worth the better shifting.)
