Hello BR...
.  OK so I am searching for a new ball to compliment my motiv 2cruel(65x4x20) I'm looking for something that gets down a bit farther and has more angle ..
my stats are
pap-5 7/8> 3/4^
speed-17mph
revs-around 500
45*
12* tilt

now I have raised my avg since getting the 2cruel and it carries and rolls amazing but sometimes mid-late 2nd game or 3rd game it can be too much depending on the type of bowlers bowling on my pair.. So I'm looking to get a longer and bit more angular ball to transition too..

now I would love to stay with motiv , but I am interested in lord field's new stuff along with some others so I'm kinda stuck on my purchase...these are the balls ibam interested in and will end up buying one of the below listed

#1-Motiv primal scream
#2-lord field heritage
#3-lord field judgment
#4-Brunswick aura
#5-900g dirty look
#6-lane 1 stealth bomber pearl
#7-motiv primal impulse
#8-motiv  thrash frenzy
#9-motiv raptor attack

so I'm asking for a little help suggesting the correct choice based on my stats... Cause I at this point can't decide ha ha ...thanks BR friends.

With that being said, I think you're on the right track and have a good option with the Primal Scream.  You'll still get similar overall hook compared to the 2Cruel.  However, the Primal Scream will go a little longer down the lane and will provide some more backend.

The Aura IMO is going to be very similar to what you have in the 2Cruel and would read a little earlier with its solid cover.  You may want to consider something such as the DV8 Hell Raiser Terror (Brunswick's sister company).  The Terror's pearl cover is known for being clean up front, providing lots of length, and has an extremely angular motion on the back.  It still can work in medium-medium heavy conditions and would provide a compliment to the 2Cruel.

yeah the primal scream is really looking like a solid and smart choice.. Mainly cause its designed to really do what I am looking for compared to the 2cruel.. Of all the balls I listed those were my inital choices...but over the last few days and lots of research I am really looking at only 3 the primal scream,900g dirty look,lord field judgment....i really like the core in the heritage tho.. And the fact a pearl particle would be a great transition piece if put at say 4k and polished cause it would still be clean but still have the angle and control thanks to the pearl/particle....

You should post this in the Motiv forum.  I am sure the ball staffers there will be able to answer all your questions about Motiv equipment
 

I would of gladly posted in the motiv forum if it were only motivs i was looking at...but I figured this section would get me the best opinions from those who throw all brands..
