Low Friction Poly X's For Gut Mains : Softer Alternative to MSV Co-Focus?

[ChicagoJack]

Hi All,

I really like the spin potential of Gut / MSV Co-Focus. Sticking with the low inter-tring friction concept, any reccos / thoughts about a slippery poly that is softer than CoF? There must be somebody out there who's wandered down the same path, looking for slippery, and a bit more arm friendly? I've cross referenced the string friction rankings [1] with string stiffness, this is what jumps out at me so far:

Hybrids: Stiffness of both strings added together, then divided by two. Note: Mains determine the playing characteristics much more so than the crosses, so dividing by two renders the estimated total stiffness a bit flawed when comparing this ledger to the stiffness digits of single strings above.

Honorary Mentions: String that isn't in the friction/stiffness database, but is described as one of the more comfortable polys by experienced members.
