A stock TT Bandit OS is about 9.9 ounces strung and is 6 points headlight. I added about 4.5 grams to the head, making it even more head heavy. Yesterday, I added some NAILS to the handle. I measured it today and it's ~336 grams or 11.8 ounces. It is definitely head light now. When adding the nails, I used foam to cushion it. However, when I got on court and hit with, MAN! If you make an off-center hit, then the nails will rattle so loud that somebody on the far side of the courts can hear it. What other materials should be used for counterweighting? How can you cushion them so they won't rattle around? Thanks in advance.
