Project Grip is a Latitude 64 premium blend that combines two of the brand’s premium plastics into a grippier one, without going soft in structure. It’s in the flex premium class.
That makes it the Latitude option for players who find Gold Line too firm in the hand. One mould is listed in it on this site.
It’s a smaller line than Gold Line or Opto, and it’ll beat in a little faster than either.
