I will soon be receiving 2 Wilson K Pro Tours that come with leather grips. According to TW the specs strung are: Weight: 11.4oz / 323g Balance: 8pts Head Light and it's a standard lenght If I take the leather grip off and just use 2 over grips, what approximately would the balance be? I don't need exact, I just want a rough idea. I have no idea how much a leather grip weighs. Thanks for any help you can provide.
