The new Hammer Spawn is one of newest and most versatile balls released this year! The Hammer Spawn features a low RG/higher diff Gauntlet asymmetric core wrapped in the same coverstock as the Zero Mercy Solid, with the additive HK-22 C2 added to the coverstock. This new additive creates incredible versatility on multiple lane conditions. I compare this ball to the ever-successful Hammer Envy Tour, which in my opinion, one of the greatest balls ever made! My Hammer Spawn is laid out 55x4 3/4x30. This layout was chosen to allow me to use this ball more on tournament conditions whereas the oil is very long, flat or has excessive volume. This ball is a ball that can be used on multiple land conditions and also versatile enough to alter the surfaces to fit your needs. IF you loved the Envy Tour, then the new Hammer Spawn is a MUST to have in your bag. Clean, smooth, hits hard and very versatile….everything a bowler is looking for in a bowling ball! The new Hammer Spawn is available in your local pro shop!
