It's not for everyone, but I think they are great with poly in the low 50 range, especially for mid to mp users with dense 18x20s.
If your stringing machine has a semi-decent mounting system, you can go 10 lbs lower on the poly than on gut and not see deformation. Polys are just that much stiffer.
I should add that I am talking about VS mains and poly crosses, not the other way around.
