Every bowling center, oil pattern, and individual bowler presents a different set of challenges.  Sometimes the very aggressive early rolling balls work great on a heavy short pattern, but like Conspirator said may not cut it on longer pattern, at least not without a surface adjustment.

There was one synthetic house that gave me fits.  All my reactive polished and reactive pearl balls would just jump when they hit dry at this place.  Then once they really poured the oil on but did not clean the back ends.  It seemed like a flood.  So I tried my Columbia Action and it worked great here.  

Then even when they cleaned the backends I still used that ball on the shorter pattern and it never jumped.  It made the lane play like heavy oil because it read the front part of the lane.  The weaker reactive balls wouldn't read the head oil but would just jump when the hit dry.

The point is to match the ball to the lane conditions and sometimes this will surprise you.  I would have never thrown the Action there except for that one bad day.  I always thought it would be too much ball.

I don't own a Mammoth so I don't know if it would work for you there or not.  I would ask one of the Brunswick Tech guys that frequent this forum. They can give you the right advice.

Of the balls I own, I know for me the Strike Zone would be my best bet at a longer pattern with carrydown.  I would move to the left as far as I could to get the best head oil and least carrydown, in other words don't play the same line as everyone else and try this.  If this doesn't work, then your other option is to play a more direct line as someone else suggested.  For me this might be standing with my right foot at right gutter (right hander) and throwing the ball over the three board at the targets (in other words to the right of the first arrow) with a more up the back release, really stay behind the ball and play direct.  Try these two methods and see what works best for you.

Good luck!
