TW matching service

[tennis_always]

Folks,
Are all the measurements on the matching serving label done before stringing? I bought a couple of RF97s which came in at 341g static weight, 12 points HL and 303 grams swing weight.
I am assuming that these are all unstrung readings. If Yes, they are all as close to the spec as they can get. Else, they are all way off.
Also, how much does a natural + poly hybrid increase the static and swing weights?
Thanks.

Yes unstrung and keep in mind plastic is still on the handle so they compensate for that. Nat gut is a bit heavier and depending on gauge of strings you use on hybrid would make a bit of difference too. Conventional wisdom for poly string job is add 15g to weight and 30pts to SW. Some polys weigh, for example revolution adds around 18g. Anyway it’s a guideline so you get the idea
