Back once again to ask the board what to add to the arsenal.

My Stats are 17mph tweener, PAP 5 3/8 and 0 righthander. Med to Med - high Axis Tilt.

Current arsenal is Nexus f(P+F) Drilled 60x40 Pin 4 Surface factory
                          Revolver 4 x 4 with a hole Surface factory
                          Massive Damage 4 x 4 Surface factory
                          Karma 55 x 45 pin 5 Surface 2000 dull
                          Avalanche Urethane 5 x 5 Surface factory
                          T - Zone for Spare.
There aren't alot of Brunswick guys down here in Global 900 country so I am looking to add two new pieces to the arsenal because I have a couple of regional tourneys coming up and I feel I need to fill a gap between my Nexus and my Revolver. The next stops are Cheetah,Scorpion and Chameleon. 
Any assistance from you guys would be greatly appreciated.

Yes, add a Versa Max. That ball is simply amazing. Other than that your arsenal doesn't look all that bad. You could also add a Pink/Purple Karma to add under your Solid Karma. I would also possibly look into replacing the Revolver with the C System Maxxed out once it is released on 8/8/12.

The Versa Max has been reliable on Cheetah and Chameleon, but for Scorpion, which is very slick, you could add some surface to the Revolver (1500-2000) and it should be good. The Revolver cover is quite strong.

If you have some time the new C-System Maxxed Out looks like it will be strong and smooth. The Nexxus P+R handles volume well, too.

My Massive Damage was great on Chameleon. Best of luck to you.

Thanks for the replies again guys. The overall consensus is the Versa Max!  This looks to be the gap ball between The Nexus f(P+F) and the Revovler. Probably will add either and maxxed - out or a Nexus f( P+R) leave it dull and Shine the Nexus f(P+F). Thanks guys. Any more suggestions would be greatly appreciated.

I would think about getting a weak ball to go under your Karma, because sometimes the Urethane is still weak on dry lanes. Think about a Damage, and leave it shined, or maybe a Karma Pink/Pearl.

I agree with the Karma pink/purple not being under the Karma solid! Mine has a lot more movement and can make it back from places the Karma solid can't! I have a pin down and pin up Versa-Max and I can't say which one is my favorite. The pin down reads sooner and continuous, where the pin up is longer and more angular. The Nexxus is really strong throughout the whole lane. The new Nexxxus is really going to fit nicely with the added pearl to the coverstock. My Versa is my benchmark ball and the Maxxed Out may take place and I can't wait for mine to ship this week. The C-System line being symmetrical is probably my favorite ball line, as it's more versatile for me. I would hold out for the Maxxed Out or if you can't wait drill a Vers-Max and add a little surface!!

I would agree with getting a versa-max.  The ball is very special and can handle medium to lighter volumes of oil with a unique motion on the lane.  Like noclay said, scorpion can be slick depending on the lane surface, by adding a 1000 or 2000 surface to your revolver and/or the Nexus f (P+R) should be a good match.  As for cheetah, you might want to look at the Slingshot ball to help control the reaction on the lane.  The versa-max might match up as well on cheetah, but you might have to take it to a 4000 surface.  Also, I would agree that the Pink/Purple Karma is a little stronger than the Blue/Green Karma and can handle a little more oil.
