I'm trying this concept. I have a 400cc driver on a very light (55 gram) shaft. I hit it pretty good, but it feels too light. Tonight I blew off the grip and added a 1/4 x 2 1/2 inch carriage bolt with 10 nuts and 1 lock washer (about 30 grams)into the butt end and blew the grip back on. I went right out and hit 3 very good drives. I can't wait to play tomorrow. Seems like it might help reduce throw away!
