Well i have the Roach in JB, Ti and Big-Z. . and i have the Proxy, Pure, Ruru, Marshall, P2, Reko. . heck i have most of the straight flying putters out there.
But as i have the LUNA as my puting putter i prefer to hav the same moul as my thrower
Curious how much $ you have invested in the Luna. Do you have a stack of practice putters?
