The one hybrid I had highest hopes for was WC Silverstring 1.20 in the mains and X-1 in the crosses.
I had done lots of research, and believed that these two were the Rolls Royces of poly or multi, thus hybriding them would be the best of both worlds.
Boy was I disappointed when I hit with it. It was way too soft. I had never understood what people meant by "playing like mush" before, but now I understood.
It is possible that I strung them too low, but I just put them in at my normal tension I used for 20 or so hybrids before that. (But I concede they two might work at higher tensions.)
Common Sense is what tell us that the world is flat, and the sun revolves around the earth.
