What are the conditions you're bowling on?

The Green Mamba is good, no doubt. But if you are bowling on some light oil, you're better off with a Bull Whip or a Wisdom, depending on the breakpoint shape you want.

After drilling both lines of equipment the 2 that stand tall are the bullwhip and the freight train...Bullwhip-If you have any side tilt drill this pin down kick the cg to the right and use a large hole 3-4 off the midline-This drill even though it is simple allows this ball to play deeper even in oil with a very aggresive move off the breakpoint.

Sure Thing has been a pleasant surprise so far this league season.
Has worked well on my THS conditions so far.
Did some minor surface changes to it to smooth out the squirtiness of the out of box condition.
But I change almost all ball surfaces at least once or twice.
This way I can replicate them again in the future.

Depends a lot on your stile and volume of conditioner you are playing on. The Freight Train is going to need some oil to keep from either burning up or hooking too much. The Sure Thing was really smooth and a nice choice for a lot of house conditions, I was calling to order mine when I found out about the PBA decision. The Bullwhip is very strong on the back end and have already put together some good scores with mine standing left and swinging the lane. In my house The Look is too strong but it ended up being a great choice on the Scorpion which happens to be 41 feet. I also liked the way the Green Mamba rolls, but a key to the SRC core is letting it do the work. I had not been successful with any of the Bank line until I started learning to use the core to my benefit and stopped forcing the ball.
