right.... been doing some thinking about this, and there is alot of plus's and minus's maybe 1 piston would be easier to do, i wouldn't have to worrie about 2 TPA's or having 2 pistons made etc, but what size piston would i need? because i reckon 20mm piston would be way to big, adam did that lever you put the link up for have this piston? but im really after 1 finger lever, not some massive 3 finger moto brake. abit busy atm so i'll re-edit this post later(N)
