I have a blended set of TS4 / TS3.  I currently only have the TS4 in the PW an GW, but LOVE The clubs.  I’m thinking about swapping out the 9 and 8 as well for TS4 heads.  Do you know what the bottom of bore to ground measurement of those to clubs are?  I’m wondering if I can just swap the heads or if I should just build a whole new club.

Thanks!
