I have 3 V9's 16x19.
Strung specs with overwrap and dampener is 328g static weight.
The static weights of all 3 are within a few grams of one another, which was a pleasant surprise given Wilson's notoriously bad QC.
2 of them had the same balance point, one was significantly more head heavy.
After few months of playing with all 3 I noticed one of them always felt more sluggish to swing than the other 2 which felt pretty much the same. I brought them in to my stringer to have swingweight measured. Turned out the strung swingweights for the 3 frames were 311,319, and 330!
330sw is too high for the game I play. So I've matched the other 2 at about 320sw using some lead from 11 to 1 on one. Also put a pennie in buttcap of other to match balance point. So I have 2 matched frames which i love, and the 3rd with the higher sw is basically an emergency frame for the extremely unlikely event i break strings on other 2 during one session.
2 Matched frames are:
328g static weight
33cm balance
320sw.
