If you had to name the top 3 coverstocks and top 3 cores Storm has ever produced, what would you choose?

I've only just been back to the sport for about a year and half after a seven year break so I haven't used a lot of them to list mine. From what I have used I would have to say:

Cover:
1. R2S Hybrid/Solid/Pearl
2. TX-16
3...?

Core:
1. Inverted Fe2
2. C3 Centripetal
3...? (RAD variation?)

For me it goes something like this:

Core - Nucleus, C3 Centripetal, ...?

Cover - R2S variations, NRG variations, ...?

Having trouble filling in the third spot for both categories. Sure would be nice to know what the various Roto Grip covers actually are in regards to what they're called for Storm balls. I'm 90% sure they use the same ones between their two lines, just with different names. As for cores the Paragon would definitely be up there for me but the longevity isn't quite there overall. Will probably be brought back fairly soon though, Storm seems to be on that kind of trend lately.

What was "the hit" ball that used R2X?
