4. The repro grips are potentially a goer, providing I can source the best example possible as a prototype. Am even prepared to leave $100 deposit with a sponsor who could let me have it for a while (remember, I am outsourcing manufacturer to SE Asia and things work on rubber-time).
I'd be very keen to grab a couple of pairs of grips if you do end up going a head.
I don't think my current grips are in great condition...well not better than the ones in your photos. I will however double check.
