He might even be using it had he not discovered Discho Microfibre.
I just got a reel of the Gutex Ultra 17 to use as my go-to racquetball multi and as a power cross for poly.
Of the polys, Vendetta, Blackout, and PlusPower all seem quite friendly.
The only issue is tension maintenance, but that could be said for many high priced strings as well.
