I would dump the strong RSP due to the fact that if your Battle is too much ball then odds are that RSP probably would be too, then all you have left to go to is a weak RSP and a Mercury. I would try to go for a SSSE/Horizon/RS1/RSX thats drilled strong (4" pin, Mass Bias 70 Degrees) and then tweak the cover as needed depending on the length of the pattern that day. If I was a betting man, you will probably put more miles on that ball than the strong RSP.

The "Strong RSP" is actually a little deceptive... I actually find this not overly strong (probably due to so much use) but is drilled 4" with strong CG (thats what i meant by strong).

The battle should is far more agressive than the dulled RSP.  My 2 RSPs are two of te best balls I've ever owned and were the foundation of the arsenal.  The covers are so versatile, and I reckon if ater practising on the tournament patterns that the dulled RSP is too close to the Battle, I can polish it or at least sheen it to make a bigger gap between it and the Battle.

If I was going to a tournament were I might expect a heavy/medium/light pattern, I'd be right with you on the spread of the arsenal, but on the long/short format, and not a tonne of games on each oiling, I dont know how useful a medium pearl/solid reactive would be... When practising recently though on patterns for the event, I found that once my strongest ball stopped working, the Polished RSP from deeper was the best.
