I am trying to match the bounce and grind of an older 56degree BV Spin Milled wedge.   it is 11 degree of bounce, so 56/11, but that is all that I know about that wedge, as there are no other characteristics of grind identified.    I would like to be able to buy a 58 degree BV wedge, in either the SM-8, or SM-9, that has the same characteristics of the older wedge.   To be able to buy a 58 degree with identical (or as close as possible) characteristics, what bounce/grind should I be looking for?
