So guys, i've bought 3 TT Graphite mids some years a go. Two of them are grip 4 and the other one is grip 3. One of the grip 4 racquets broke on a mishit and i was left with two different grips, a applied a heat shrink sleeve to the L3 to transform it on a L4. But the racquet feels way different and the weight difference is about 12g. How hard would it be to install the pallet from the broken L4 racquet on the L3 racquet?
