I want to add lead tape to my Prince O3 Hybrid Shark OS to make it swing heavier. I have the Unique Lead Tape and it says to cut 4, 4-inch strips to put on the racquet. I looked on Racquet Finder and it says the weight of my racquet is 10.3. On the back of the lead tape package, it says each 4-inch strip is about 1/2 a gram. How many strips of lead tape should I add to make the racquet swing heavier? Should I also put the strips at the 9 and 3 positions? I looked at the TW Customization tutorial and I believe 9 and 3 are the correct positions. Will adding lead tape get my racquet to 11 ounces?
