Hi.I am a little unfamiliar with swing weights so I can use some help. I originally purchased a 910 D3 driver, 910FD 15* , 910 f 19* and a 910H 24 * all with standard grip and Ahina 72 shaft. Since my first purchase I have changed the grips on all clubs to a Decade mid-size multi compound (59 grams) and I also changed the driver shaft to an Ahina 70. Can someone tell me which weights to use to get the swing weights back to factory weight as the headsfeel much too light?

Thank you in advance.

Jim
