I'm really like the DV8 stuff I've thrown and was considering going strictly with them.  Only problem is that if you listen to their promo stuff, it's all go long/big backend stuff. 

Now, I know this is just hype, but it makes me wonder if I should blend in some Roto Grip or even something from Hamumbianite for a heavy oil/smoother reaction.

Yes, I know I can do just about anything with drilling/surface, but I still think there is something to finding a company you like and working within their line.

I'm early in and will most likely be looking at a wide range of stuff, but I'm up for suggestions/discussion.

When I think arsenal, I'm looking at something along these lines (I'll put in what holes I've already filled)

Raw hook
Strong pearl/hybrid - Brutal Nightmare
Benchmark - Diva (not drilled yet)
Benchmark pearl
Weaker pearl/solid - Misfit (but this is up for debate considering I haven't thrown it on the proper condition)

There are also niche holes to look at such as a mid range that pure roll, weak low end ball for fresh short (rolls earlier and compliments other weaker piece)

I could go on with specific stuff, but we all could.  Essentially, I'm looking at the raw hook and medium pearl.  I know Storm/Roto make great pearls and I'm not sure on the raw hook with DV8.  They really could do a better job of toning down the "looks like somebody kicked it" backend hype.  Most of us want something that chews on heavy fronts and gives a good mid read.

Feel free to comment/suggest. I'm keeping the DV8 stuff I've got, so don't pitch me another company.  I am trying to figure out if I want to just go with a Ruckus Feud/Endless Nightmare for the juice and a Diva Pearl or if there are better options.

Heck, I'm just in the mood to talk equipment and play catch up.

I think you answered your own question at the end.  Ruckus Feud would certainly fit up top, and the Diva Pearl would be a nice complement to the Diva for Medium. There are balls still available (and some relatively cheap at this point) that could serve niche needs.

I agree with Snakster that the Ruckus Feud would be a good strong top of your line ball. I was impressed with it because it is controllable and has a strong hook motion even with a pin down drilling. Also, the Diva Pearl is a great compliment to the Diva and would serve as a benchmark pearl ball in your lineup. The diva pearl clears the front part of the lane easily and still has a good strong motion on the back.

Per Gizmo823's comment about a cleaner reaction, I would suggest a Dude. The Dude would fit under the Diva and has a smoother overall motion on the lane. Both the Diva and Dude take well to surface changes.

I think you made the right choices here.  The Diva/Diva Pearl will definitely do well as the benchmark.  I also agree with the Ruckus Feud/Endless as your top end.  As Gizmo mentioned and having seen both thrown in league, the Feud will roll a bit earlier and would be a bit smoother overall compared to the Endless, where you get a bit more length.
