Drilled it last night, came with a 4 inch pin and 4.4 oz. top. Have the pin way above the ring and the cg right in the middle of my palm. threw it at a spare, not altering my release, hook past it. threw it again, flat handing the ball, my usual way, went straight as an arrow if not straighter than my spare ball. Got to bowl on some dry also, moved nicely, not violent but hits. I'm impressed.
