V1 is Lone Star’s Victor 1 plastic, and it’s a plastic, not a mould version. Soft, ultra-tacky, made to grab chains and stop on landing, and it floats.
That makes it the Lone Star putter plastic for the short game and for water courses. Five moulds are listed in it.
It goes gummy in heat and it isn’t made for drivers. V2 is the firmer version.
