Martin Flourocarbons vs Oasis Warms vs Martin Graphite Polygut

Aloha UU. I use Martin Flourocarbons on all my ukes. Been experimenting with different single string offerings for low G. I'm curious though if any of you have experience with Martins and Oasis GPX warms on same tenors and how would you say they differ in sound? Feel? Tension?

Also, anybody use the Martin premium polyguts?

Mahalo in advance.
