Head Extreme Tour pre- and post- stringing balance

Djinn

Semi-Pro
Has anyone measured the balance of their Head Extreme Tour before and after stringing? It doesn't matter which strings you used (let me know anyway!), I just need the balance change for references.

I went through hell finding 4 Nite Edition Extreme Tours that were close to matched and was lucky enough to find them. After adding leather grips to all, I have the following UNSTRUNG specs:

Racquet
Weight (g)
Balance (mm)
Swingweight
A
308​
307​
281​
B
308​
306​
276​
C
306​
307​
277​
D
308​
308​
282​

My intention is to weight these up to my spec, about 340g strung with 340 swingweight. So I want to add weight before I string them because I want to add weight under the grommets. If I string first, the grommets will need to be replaced before I can add weight. The grommets for these racquets have been impossible to find so I definitely need to add weight before stringing. I also need to match the specs beforehand. Because I cannot string the racquets before customizing them, I cannot calculate exactly how much weight to add and where without knowing strung balance. If someone is kind enough to give me a before stringing and after stringing balance change, I can use that to calculate what my strung balance will change by and calculate the rest. Thanks!

Thanks for the info. Is this a measured value or an educated guess? I'm just trying to get them as close in specs as physically possible.
No prob. Yup I’ve been playing the extreme tour since launch and that’s based on my experience.

You really want to match the frames’ balance, mass and SW wiithout strings, etc. You can have your pro shop or TW do it for a fee per frame. Once matched, you can use the TWU calculators to see where to add lead. String matter as SW can change by 20 Kgcm^2. If you are doing this yourself, do not start with numbers from racquet finder or the manufacturer. Racquet finder is an average and manufacturers have allowable variances. FWIW I would not put lead under the bumper guard. What eould you do if you decide you do not like the SW?

Thanks for taking the time to offer great explanations for everything, your comment is super helpful for probably 99% of the people on this board. I have my own scale, balance board, SW machine, and stringing machine though. If I had the option, I would 100% get them matched from TW, but everywhere is sold out and my local "pro" shop doesn't know the first thing about customization. The stats I provided were measured by myself, very precisely, using the equipment I have. I will be using the same string setup in all 4 racquets. I just cannot string them before matching them because I want all my lead to be hidden under the grommets and I can't find new grommets because they are sold out everywhere. I am also sure of the specs I want because I have been playing with those specs for a long time. I went as far as putting lead at 3 and 9 o clock on my Gravity Pros...on the outside under the grommets just so it would be hidden from sight. I get super picky about details, that's my problem to solve. Just wanted an idea of how much strung balance would shift so I could have a concrete number to use TWU calculator. Thanks again!

Mine was 302 grams, 317 mm balance unstrung. After stringing with 1.30 poly string it was 318 grams, 327 mm balance, 321 SW.
