Inside of 8 yards CG64 is awesome chipped provided it's from fway at worst.
Particularly steep down hill and on champ greens (talking cleve only) the chip offers the most control. Above that I would pitch almost invariably all the way up to 18/19 yards. The spin on the cleves, controlled properly, practically renders the need to flop redundant. More than one way to skin a cat, if ever there was one though, I fully accept.
My 2cents:)
