Yeah, I'm not normally one to customize as I prefer to find the stick that is just right for me 'stock'. But if I really like the VCORE Tour 97, and the 330 is too heavy for me, I may have to investigate some customization.
I haven't played w/ a leather grip in over 20 years, but I'm more interested in the added weight than anything as I use overgrips as well (usually Wilson, but am trying Supergrap this week). 310g just sounds too light for me, but maybe it will be OK.
