I have a set of Modus 105 shafts with no heads. I’m considering some used Mizuno heads 5-PW but was told they’re BU heads so lighter weight and 2 degrees upright. I can get the heads bent back to standard but not sure what to do about the lighter heads. I heard it’s about 7 grams lighter than standard. Any best practices? Lead tape looks ugly so I’m considering shaft weights.
