I have used Champions Choice with the gut in the mains at 50 and the Lux ALU rough in the crosses at 48.
It seems this is the only hybrid you mention that uses gut.
This has been reported as the setup that Federer uses or did use. He may have moved on to something else.
I liked it a lot, but like Lux 4G in the crosses better. You still have the problem of the poly needing replacement a lot sooner than the gut.
