Used to multi but open to poly too. Does a string like that exist? I like X one in my ps85 at low tension, but multi is so so for me in other frames. I like Cream but it is a bit harsh and not good at low tension. 4G is ok but a bit wire like, any suggestions? A more controlled multi but still crisp, or a softer poly that is also still crisp...
Multis & polys have very different characteristics. If you found Cream harsh then it’s going to be tough finding any poly comfortable.
I recommend trying one of the tecnifibre all-in-one hybrids like triax or HDMX. They are essentially a blended multi/poly and sometimes others ingredients, all in one string.
Other than that, Velocity is a more controllable multi, but still very much a multi.
Ashaway Monogut ZX is another interesting option. It’s a Zyex based string. Zyex is powerful and soft like a multi, but smooth and slick like a poly so provides a bit crispness and more control through spin potential. It can be hard to track down, but it is available.
A hydrid of your NXT and a soft poly, like Cream, might also provide the feel you are after.
Best of luck.
