Im looking to build a complete arsenal for my daughter who is competitively bowling a Jr tour in our area so she is strictly bowling on sport patterns with the exception of 1 league which is on a house shot. She is 15 averaging 175 on the sport patterns she throws the ball 16mph and she is a high track player. So I would welcome any suggestions for an complete aresenal. Thanks

First and foremost, Sigma Tour... This will be her favorite ball IMHO. Extremely versatile ball.

Second, the Primal Scream.. This ball just clears the heads great. Some people may say the 2 Cruel but I think the Primal is more than enough ball for wet conditions.

Third, you may want to break out the Sniper...

I have rolled the Venom Strike and wasnt as impressed with it as I thought i would be. Going to throw it on some different patterns first.

You cant go wrong with Motiv.. Good Choice..

Which Sigma Tour would you go with? And she was looking at the 2 Cruel. Her current arsenal as of right now is a Out Burst for oil, Freeze Hybrid med to dry, and a C System Ulti-max med to dry, She has only been bowling competitively for a year now and has just had my hand me down equipment.

Heavy Oil: 2 Cruel or Primal Scream
Medium: Raptor Attack (this ball needs more love)
Light: QZ2 Backdraft
Dry: Ascent Solid
Spare: Sniper
All-around: Sigma Tour

If I could redo my purchases, this would be my arsenal.

The Sigma Tour is the black ball.. The red Sigma is the Sigma Hybrid..

I would consider talking to your pro shop technician, first of all. Nobody here has ever seen your daughter throw a ball, so we are all making educated guesses.

If your daughter is beginning competition on challenging oil patterns it is vitally important to start looking at patterns from front to back as well as left to right. The left to right reading of a lane is all that most league bowlers do and that is not nearly enough for attacking sport conditions.

That said, I have no clue how many balls you have in mind, but the best thing you can do for assembling an arsenal is to have balls that range in the amount of friction they create on the lane (left to right hook) and vary in their speed of response (smooth to angular).

In a perfect world, a bowler's arsenal would be at least 5 balls (6 if you use a polyester spare ball).
1 for general heavy oil use (moderate speed of response)
1 for general light oil use (moderate to fast response)
3 for medium oil use (slow, moderate, and fast response)

As the product line stands, I would likely end up with:
Raptor P7 or 2 Cruel (Heavy oil, general use)
Venom Strike (medium oil, slow response)
Sigma Tour (medium oil, moderate response)
Primal Scream (medium oil, fast response)
Ascent Pearl (light oil)

I tend to post on here a couple of times a year and when I do it's too long. Sorry about that.

Thank you all for the information it is very helpful, I was just looking for a place to start, our local pro shop does not have very many MOTIV bowling balls as no one in WY really throws MOTIV so there really isnt a demand if you know what I mean, I just recently purchased one a SIGMA Hybrid & I absolutely love it and I plan on purchasing more and I know my daughter will like them as well I just didnt know where to start her arsenal with MOTIV so I just figured I would ask the people that throw more of the equipment as I really dont get to see the equipment work first hand. So thank you again for the suggestions & keep them coming in, I have a great feeling that if it got more exposer out here in WY it could really sell.
