Alright - the fall/winter season is very close. I'm looking to tweak my arsenal. I will be bowling on wood lanes in 2 different leagues ( same house ) and synthetic on 1, possibly another.
Current arsenal is:  DEFIANT   ---- CRITICAL THEORY --- RISING STAR ------ Crossroad ---- Resurgence Revival

I will be adding the ---- BERSERK -- SHATTER -- I want to stick with Roto so the Resurgence will be sold.  I will probally sell the Crossroad as well because it does not match up well with my style. If anyone  has thrown the Berserk or Shatter, I would love to here what you have to say about them. thanks for your input.

 I had picked the Shatter, mainly for lower oil volumes and for the wood lanes. Due to my higher ball speed  (16-17mph), I thought the Shout /Scream may not be able to recover for me, that is why I am going with the Shatter.

If you are reading 16-17 mph at the pin deck as most people do (using the machine built into the lanes) you can be anywhere between a medium speed to high speed bowler depending on revs. and how direct you are throwing the ball.  If you are a high rev. guy swinging the ball inside out 16-17 at the pin deck is pretty high speed. off you hand is most likely around 21-22 mph.  If you are a stroker playing up the track getting to the pin deck at 16 you are letting go off your hand approx. 18 mph. and you are a medium speed bowler.

As far as the arsenal is concerned you are saying Defiant, Critical Theory, Berserk, Rising Star, and Shatter.  The only thing I would have done differently is to have a medium solid for a different roll - maybe a Shooting Star.  Otherwise It is fairly well balanced.

I now have the all ROTO arsenal as stated above.  The Berserk and Shatter are very impressive. I just picked them both up this past Monday, so I am still learning how to play them. I can tell you that the Shatter is stronger than I thought it would be, meaning once it hits the dry it makes a strong move, but not uncontrollable- and it does Shatter the pins. I did think about the Shooting Star, but I prefer hybrids or pearls. Regarding the speed, according to the qubica monitor I was mostly around 15.23 - sometimes down to 14.83 and up to 16.24 -keep in mind I was experimenting with the way each ball would react. my question is how accurate are the scorers?  and when do they read the mph? my guess is at the pindeck? I would say that I play more down and in, but I can also play a tweener type of shot as well depending on the lane conditions.---- Bottom line - I believe my line up will get the job done!
