I'm not sure if this is in the right section but I don't feel it belongs in any specific brand forum because I'm open to all brands.

I currently have a 2 ball arsenal of a No Rules Pearl and a Dare Devil Trick. I throw about 15.5-16 mph and have medium ball revs. With a normal shot both of my current balls are fantastic but I've been noticing the houses seem to be laying out less oil now and it's turned in to a stand left and throw right shot. It's something I can do but it's not my normal game. I've also been ramping up speed on my ball to make it work but for me, high speed is bad accuracy.

I've looked at the hustle and it's a nice ball, and my PSO suggested it too, but he's a storm roto grip guy. I've always said that unless a company is paying me to throw their stuff then there's no reason to exclusively throw it. If one of the hustles ends up being the best light oil ball for its buck then so be it, but I'm wondering if you guys have good experiences with anything else that I can look into more.

Big criteria for me is good bargain for a quality ball with decent movement.

Thanks in advance

The biggest problem you run in to balling down comes if you can't Stay far enough right you are going to lose hit.  My feeling is that you don't ball down From the NRP as long as you can keep the ball in the pocket from deep inside. 

As mentioned already, polishing the DDT would put it closer to the NRP, not farther away. Ideally, You start with the trick, then switch to the NRP as you migrate left and need recovery that the DDT can't provide when getting too deep.

Now if you're looking for something on the burn to jump back right, there's been some good low end performance balls mentioned.

My philosophy is ball up to move left, ball down to keep right.

This is going to sound weird. But in the heaviest of heavy, I have my best success with the DDT. Once it starts breaking down a bit, I have more success with the NRP. From there I can actually transition back to the DDT. The NRP is more ball than the DDT for me, as the lane breaks down I switch from the NRP to the DDT to stay right. It's just I get a better reaction with the DDT on very heavy oil

Exactly. DDT has a slower transition than the NRP - and the original Daredevil. It is stronger front to back, but does not have the back end reaction of the others. Due to core shapes and layouts, my DD actually covers the most boards of the 3 - most of the time anyway. It can depend on the amount of head oil. But generally speaking (house shot anyway - haven't had a change to throw these much on sport yet), I have it this way:

Strongest front to back: DDT, NRP, DD
Fastest transition to the pocket: DD, NRP, DDT

But again, DD and NRP could probably flip spots depending on drilling, surface, and how you throw it. And a polished DDT would likely bring it closer to the NRP. Still should have a different motion though.

As for the topic, as others have said, you will have to decide how much separation you want between those 2 balls and your "light oil" ball. Something in the Hustle line may be a good fit, or you may need to go weaker - like the Tropical Storm. Or you may want to keep things closer and go with something in the Wrecker line or Hy-road line (or similar) from Storm.
