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.
