I recently drilled up a BIG BRO KO by Swag. This is a very smooth big hooking asymmetrical pearl ball. For having such a low RG the ball did not have a heavy roll to it. It cleared the heads with ease. I drilled the ball 55 x 5 1/8 x 40. I left the ball at box. If you are looking for a reliable and predictable pearl asymmetrical ball, dont miss out on the Big Bro KO.
