I'm using it in my racquets with more open patterns - 16 mains - including my Volkl C10's and Yonex RD Ti-80's. It's not so fragile in that application compared with 17 ga. syn. gut and also rather easy to dial in the tension. In a more dense pattern, I like the feel I get with 17 ga. syn. gut, especially with my mids. The thicker strings all crowded together can just seem too clunky for me.
The two syn. guts I'm stocked with right now are Gosen OG Micro and Tecnifibre reels, but I've always liked Prince Original Syn. Gut, too. (not so fond of their Duraflex product)
