So far all the rackets i've ordered are heavier in weight but only a few points off in swing weight. the balances are all spot on. To me i find this wonderful. Not only do i get a racket of my preferred weight, they only need minimum customization when its required.:twisted: For instance i got a Diablo Mid friday. it was already heavier than 12.2 ounces. i would say 12.6. I then replaced the syn. grip with a leather grip, and now it feels similar in weight to my speed pro and all i did was add a leather grip. :shock: So who else has had positive experiences with QC issues.
