Continuing my experimentation with non-Brunswick equipment, I purchased this ball for a summer "pro" league at Southwyck Lanes in Toledo, OH (home of the PBA National Championship). Last Wednesday, we had the same PBA lane condition that was used last February in Latham, NY. A sixteen-pounder, drilled 3 3/8" X 5" with four ounces of top weight, this baby worked well when the shot broke down after a few games. I'm a righty, and I used the first arrow for most of the evening. The Assassin has an extremely powerful hit and carries well on a down-and-in shot. Being a semi-cranker, I left few corners, but did leave an occasional 8-pin or 9-pin! The large top weight enabled the ball to "loaf" down the lane while maintaining the low-RG, high-rev characteristics. This rock is great for medium oil, one of Track's best balls to date, and as a result, I won $30 in jackpot money! I'm looking at the Enforcer for the fresh shot, with its sheen finish, a 2" pin, 2 1/2 ounces of top weight, and drilled 3 3/8" X 3 3/8" for earlier roll. We'll see if the shoe fits!
