Reason for me posting here is because there are a couple balls by Hammer that have caught my eye.  Especially the Pain and/or Black Widow...

Okay, I'm trying to get some stuff this summer to last thru the first half of the winter season. Listed below is what's currently in the bag right now. I throw about 17-18 mph, getting a good amount of hand/fingers on the ball (based upon the opinions of those that watch me). My release has changed for the better recently, as I describe below, and need to revise my equipment a little. All suggestions/comments regarding drill patterns, surface preps, and what type of ball I should buy are appreciated.

Rule Delta 1
Machine
Classic Zone Green Pin
Doom
Classic Zone Red Pin

All balls listed were drilled using Full Roller patterns (However, while still Full Roll, the Green Classic has a different pattern than the other 4). I'm finding that my release has changed in the past 3 months, which is leading to my track flaring over the holes as it looks more 3/4 roll.

I hate the Delta, yet it hooks. I love the Machine, as the lanes begin to burn up. The Green Classic is one of the balls that are thumping down the lane now. Favorite ball right now is the Doom. Hit power/carry/control is the best for me right now. The Classic Red works well in that regard as well.

So what's missing? I'd like to replace the Delta1, Classic Green, and move the Classic Red to just a ball I can go and run to the car for if I ever encounter lanes that burnt. I love the Doom, so I was thinking of maybe adding the Raw Hammer Pain. I know I need an oil ball though.

I have a Vapor Zone waiting to be drilled, with an Agent that I bought for the hell of it (got a great price) on the way. I'm thinking of drilling these using 3/4 roll patterns, but not sure exactly sure which pattern or how they all would fit. Carry 5 balls with the option to go and grab the Classic Red if needed. Someone help me to line up the arsenal (including surface changes to any of the balls).
