This is the first track ball I've ever thrown, and I love it! It is the best ball in my arsenal. Drilled pin right of ring cg stacked below. I bought this ball on it's third drill for the cost of shipping, and it puts all of my other balls to shame. The house uses med oil every few days before league play, so by the time I get to the lanes for the dollar a game bowling, the lanes are fairly dry. I'd say the assassin is most comparable to my Xxcel. It has a strong midlane roll, and an amazing backend reaction. I struggle a great deal with consistency in my release, but the assassin seems to be very "sympathetic to my needs". If I roll it too far out to the right it will take a sharp turn right into the pocket (usually leaving 6 and 10. If I miss my mark to the left, the ball will go straight at the head pin, then without losing it's revs will move slightly to the left of the head pin and result in an uncomfortable strike. I average around 156, but last night with the Assassin I bowled a 194, 170, and 225. The 225 was the first time I'd ever hit every pin! On a side note, the fellow who sold it to me got rid of it, because he couldn't get it to move in oil after it's 3rd drill. On the dry, it is more predictable and powerful than Ebonite's One, Over Time, and Lane 1's Hybrid Dirty Bomb.

Look for me in the upcoming PBA Tour! I'll be the guy in the back row with the foam finger singing "Take Me Out To The Ball Game" during the 7th inning.
