I'm interested Cathy if you get numbers. Have been day-dreaming about such mods but wouldn't be game on my own. If there were a few of us, then a greater chance of sharing the knowledge around. I would hope for smoother (hopefully lower) PE curve and much reduced DEC backlash.
Might be an idea to get an extra belt per kit as spares too if doing a group buy. Be interested to see/hear how you go with this
