of the non-poly mains i have tested with poly crosses, it performed the worst in terms of friction after the outer layer got sawed through, but i only tested it with one poly cross, so it might have just been a compatibility issue.
That's why I'm focusing on trying to pair it with the absolute slickest cross possible, but also not just something that relies on silicone or wax infusion (RPM/Rough, G-Tour, YPT Fire, IsoSpeed wax-infused poly's, etc.), as those wear off after minimal usage. I'm hoping a higher-density crosslink ester, whose slickness is part of the core material, will be enough -- something in the realm of Hawk, Revolve, Co-Focus, Tour M8, Wasabi X, etc. And I'm going to string Micronite 3-5 lbs higher than the poly cross, to keep the mains as "snappy" as possible, with the poly cross more slack, to promote movement of the mains. That said, I have a feeling Micronite is just going to be too sticky to snapback on even the slickest of those, but one can hope. I'll report back once I've got a session or two under my belt.
