Today my local store received 6 ps 6.1 95 and we weighted them all together (strung with factory wilson sensation, no overgrips) and here's the results: one was 329, 2 were 332, 2 333 and one 334. Both wilson and tw specs say strung weight is 326, while unstrung weight should be 313. So my question is: are strings heavier than 13 grams (which would give 326) or are all racquets weighted differently (and all above 313gr)?? thoughts? Anyone who's got a demo or has bought one can share strung weight without overgrip/dampener?
