If your looking for an oiler, skid/flip, and a control piece, there's several 3 ball setups you could go with. All depends on what shape, and where you want to play.
Here's several setups:
Stampede - can handle good amount of oil, but still has good length
Long Horn - perfect for length, angle, and a perfect step down from Stampede
Dominion Hybrid - add some polish over surface and it's a fit for a control piece
or
Venator - can handle good amounts of oil, and it's a smooth piece
Long Horn - perfect for length and angle
Dominion Hybrid - add some polish over surface and it's a fit for a control piece
or
Raging Bull - can handle a lot of oil, nice and "rolly"
Long Horn
Dominion Hybrid
As you can see, all the setups are basically the same except for the oiler. The Raging Bull handles the most and is the "rolliest", the Venator handles the second most almost as "rolly", and the Stampede which can still handle some oil, but it has more length than the other two.
But like I said, it all depends on where you want to play, what shape your looking for, and your style.
If you wanted just a basic 3 ball arsenal for league ,where one ball supports another, than I would go with this setup.
Stampede
Long Horn
Platinum
Each of these would compliment each other out on the lanes. But you would be missing that "control piece". The Platinum could be if you took off the polish and had it at 2000/4000, but in my opinion a control piece is something that is smooth rolling and predictable, and right now I would say the Dominion Hybrid with some polish on it would fit. It would sit between the Platinum and Long Horn, but with a smoother roll than those two.
For an example, my league 3 ball arsenal is this. These 3 give me 3 different looks on the drier conditions I see.
Dominion w/polish
Platinum w/strong layout
Platinum w/weak Gunny layout
I can play deep with the Dominion with a smooth roll, the strong Platinum I can play just right of the Dominion but with more length and pop, and the weak Platinum with the Gunny layout, I am closer to the track with a smoother roll. With the lighter condition I see, it is all I need.
