I totally agree with you Mick, I suppose if I had a well sorted highly customised Mercury, it might warrant such a conversion but I don't know what one would be like with nicely honed and fettled sears etc, I cleaned and polished up a Merc S trigger block once and done the same with the alloy trigger blade and it was surprising how nice and smooth just using the trigger was afterwards, I might have to experiment one day (when I get the time) and smooth out all the pivot points and polish up everything and see what that does.
