how did bhs7t/black zone play?For hybrids I tried:
Gut/Poly - VS Mains / BHS7T Crosses works well, gut gets frayed a bit more than with slick crosses but durability is the same for me. Djoko, Fed etc do gut mains / poly crosses.
Poly/Gut - BHS7T Mains / VS Crosses - $$$, this lasted an hour and a bit sadly, felt like a dampened version of the BHS7T, initially great spin, then gut absolutely shred and popped. Several ATP players prefer ALU mains / Soft crosses (Sensation, Gut, Element or another soft cross) for a more poly feel but softer on the arm.
Poly/Poly Hybrid - BHS7T Mains / Black Zone crosses works well.
