I don't know how much weight Fairway adds as I've TW Private label leather grip on, it is about 8g to the handle and 2+2g at 3&9.
Doing so balance is 31.5cm which I like as I tend to have a more headlight frame.
I've read good things about Gamma Hi-Tech grip being very similar to leather, but...
if you want to open up the VC95 sweet spot put some lead at 3+9. I've done so and it's much better then stock. I've added a leather grip too so my specs are:
balance: 31.5 cm
the VC95 is an awesome frame
