Question
Hi,

I am a fairly low-rev stroker w/195 avg.

I throw 3/4-roll with a 14+lb urethane ball with some track flare.  (I don't know enough to quote more precise measurements.)  I've noticed that when I am throwing on a down-and-in line, I can get decent carry.  However, sometimes I'll find a line that leads to the pocket where the ball goes longer and hooks harder, or alternatively is a curve.  However, in those cases, I hit the pocket, but the ball runs out of energy at the pins, and I start to leave 10s and occasionally a 5.

I'm wondering - is there some relationship to angle of the line that can result in the ball having less energy at the pocket?  

If so, how do I keep the ball's energy up at the pins to carry the strikes in these other lines?  Should I throw faster in those cases? Does a heavier ball help?  It would have more momentum at a given speed, but I'm not sure if I will get enough revs on a heavier ball to work through oil.

My spare accuracy is good, and I usually hit the pocket.  I just need to carry more strikes to raise my average.

Thanks,
Brad

Answer
A urethane ball will have the tendancy to use up its energy sooner than a reactive resin coverstock.  This will create less hitting power and less entry angle.
I would look at getting an entry level reactive, such as an Ebonite Tornado or a Storm Tropical Storm.  These balls will give you more of what  you are looking for without having to change your style.

Good luck,
Chip
