Sir,
In my opinion, I would not go with the RS-X and the RS-1 for a 1-2 combo. Simply because the core diff. is so great you are going to have 2 early hooking pieces, and yes you can lay it out with the pin above the fingers but you will still have a STRONG midlane move.
You want a good 1-2 punch? Go with wither the RS-X or Rs-1 and the Ressurection. Now thats a combo. Now the only determining factor is how much oil you want the RS-X or RS-1 to handle. If you want a heavier oil piece go with the RS-X, for a more Med-Med hev, go with the RS-1. But BEWARE, putting an early rolling drill on either of these balls will give you just that. I own both and their pics are in my profile. The Rs-x gives me decent length and a nice snap on the backends, the RS-1 Rolls like I have seen no other Pearl roll before. I have a vid with the RS-1 just do a search for it.
But back to the point, I think that you will find the RS core and the Ressurection core very complementive to each other. If all you are looking is for HOOK HOOK HOOK, but if you want a combo that can be deadly on a pretty wide variety of conditions, go with one of the RS's and the Retro Ressurection.
Hope this helps,
BMM
