I have 3 Pro Stock 238.5 TKG's, weighted up as the retail version, 325 strung and 6pts. head light. I also have the PT630, I-Prestige, You-Tek and 4 IG prestige pro's. I have to say the IG Prestige(stock) plays better than the pro stock frames, my opinion only as we all differ. I fail to believe by adding lead in the hoop area has more integrity than a racquet with same manufactured weight. Manufacture weight meaning all the materials(graphite, etc) combined / lead on the hoop and silicone in the handle. Most pro's use racquets in excess of 325 grams, so why not customize from there, much stronger frame. Just my thoughts as we all have different tastes & feel.
