I've been using my Aura Paranormal lately on a THS with great results, even when it is supposed to be a heavy oil ball it has been a great ball on THS when my Brunswick Wicked Siege or my Sigma Sting are not enough. However, I started thinking about getting a new ball with similar specs/reaction for when I decide to retire my Aura Paranormal. Motiv is a brand that I started using this last year and I liked so far, but I'm also interested in trying Radical... So, which balls better compares to the Aura Paranormal?

By the way, I'm looking that the new ball could be used on a long pattern and with more oil than a THS, since I'm planning to bowl at the USBC Open @ El Paso this year.

Any help would be truly appreciated! 

Guru is a hook monster. The Brunswick Intregue is also an awesome ball very strong for a hybrid.

The Mastermind Intellect has been the biggest hooking ball I have thrown so far. Not tried the Guru or the Unruly. I have an Unruly on the way.

The Guru is super strong as others have said.  It hooks a bunch and is geared to handle heavier oil like no other.  The new Thug Unruly is also a very good heavy oil ball.  The closest ball oob to the Paranormal is the Mastermind Intellect.  As you add surface to both balls you would find the Intellect to be stronger than the Paranormal.  The Mastermind Intellect would potentially fill both voids in your bag.  You would just need to scuff to 500 or 1000 when you encountered more oil.  Kid lost is correct in saying that the score is probably closest to the Paranormal in the Radical line. If I was looking for an oil ball I would get a Guru.  If I was looking to replace the Paranormal I would get an Intellect, which is a little stronger or a Thug which is a little cleaner through the front part of the lane.

Yes. Your AP plus another ball for a good two ball option as needed for most conditions. One for heavy oil and one for everything under heavy oil.

Great! Yeah, I definitely need a strong ball suited for heavier conditions. the Aura still works pretty good, and it still can be used for a while, but since I'm about to retire one of my favorites balls (Wicked Siege) and I bought the AP almost at the same time as the Wicked, I started thinking about when it will be the time to retire the AP.

One of my teammates has the Mastermind Intellect and it is indeed an impressive and strong ball, it has a little bit more lenght and more backend than my AP but overall it looks close to the AP, and being a Brunswick, I'm sure it has to be the closest I can get to the original AP. The only thing that makes me think about what to get is that with so many options in the market  I don't want to get the "wrong" ball and I want to fill the holes that I have in my arsenal right now, which is the lack of a heavy ball, but I do really appreciate all your comments and advice, it really helped me to take a decision! Thank you so much for all your help! This forum is great!
