Whichever one has the longer control bore length is the one you want.
Hm well the stiffi MF series has 5in worth of bore, i think ima go with one of them. I think i prefer the quite light barrel to somthing that would match. Im thinking ima go with a 687, that sound about right or should i go with a differnt bore? I shoot crusade/graffiti regularly, my 89 is clearly overbore so im thinking a notch down will still be over but il save a bit more gas and cut down on noise
