First off, I am looking to complete my arsenal by getting a Pearl ball. Just wanted some advice on a Pearl ball that has worked well for you.

Second, yesterday was my best 3 game set this year. Second game, had a chance for 290. First frame, ten pin spare. throw next 6 then in the eighth I turn my hand to early (topped the ball) and washed out. Get the spare and strike out for 265.

Third game, go front nine. Of course, people start to come and watch by now. Getting anxious so I make sure a relax and go through a preshot routine. I also hate when people who have not said anything to me all night come and start to talk to me, but that's besides the point cuz I throw the ball. Well, I end up doing exactly the same damn thing I did in the second game. Turned the ball early and the ball did not read the lane!!!! WTF

Sorry, but had to vent

Congratulations .. good shooting! People don't realize they throw you off by talking to you .. I think most have in mind to keep you relaxed! You did well .. good man!

As far as a Pearl .. at least take a look at Motiv's PRIMAL IMPULSE ..

That does help.  Average speed and most likely average revs, you may want to take a look at the Roto Grip Bandit.  That ball has good length and a nice sharp backend.  It works well on many medium conditions and could fit you well. 

If you want something for lighter conditions, the Roto Grip Shatter is another good choice.  The Neutron Core is still one of the best symmetrical cores I have ever thrown in that line.  That ball is predictable- good length, good backend.

For medium-heavy, currently I throw an Ebonite Vital Energy.  That pearl is sanded at 4000 and gives me good length with a predictable and defined backend.  I pull that out once the lanes have transitioned or if I need extra length.  The Critical Theory is also another great piece, but may be too much ball for what you need.
