OG Micro is probably enough if it's in the crosses, I personally wouldn't spend the extra money for OG Micro JC since it'll be in the crossers anyway.
Pro Supex Big Ace is a fantastic poly, comparable to Lux...holds tension better than Lux, offers good bite and spin but last longer, is cheaper, and is softer feeling.
Same with CyberFlash.
Both Big Ace and Cyber Flash are the next generation of polys from the Lux ALU, which I believe is second generation of poly (BA & CF are 3rd gen). The key is they're softer but offer the same characteristics a poly should have, and they maintain tension better.
Do try those out
Pro Supex is not distributed by TW. I'd love to see them distribute it though.
You'll have to get it from string d e p o t p l u s dot com.
