[Calif1]

Hi guys,
First post here on the talk tennis forum!
Recently customised my Ezone 98 to these specs:
347g strung weight
339 swingweight
33.2cm balance
Would love to calculate my MGR/I, so if anybody could help me out that would be greatly appreciated, if you need any more info just let me know.
Thanks,
Calif.
