I strung a frame with a new biphase and used 120 string savers on my string. And my frame feels much heavier. My frames unstrung weight is 9.1 ounces, and biphase adds like .6 ounces, and i heard 120 savers should add like 1 grams. so the weight sould be close to 10 ounces. But it doesnt. is something wrong. i dont have any lead tape. just an overgrip. biphase is 16g.
