The lightest SW heads we have are in the TSW line or the MG Series. The 56 degree option in both are 298 grams. Probably not light enough to get you the same swing weight of a PW if the PW has a standard weight of around 291. You could counterbalance if the swing weight number is that important to you. The TSW has a 54 degree option that is 294 that would put you closer to the one swing weight variance if the PW is 291.
