KC Pro is Innova’s putter-and-approach Pro blend, named for Ken Climo. It’s a firm, opaque baseline putter plastic with a bit more durability than DX.
That makes it a feel plastic for the short game: consistent release, good grip, a slow beat-in. Two moulds are listed in it, and R-Pro is the softer sibling.
It isn’t made for drivers, and it’s mid-tier on lifespan.
