I've used just about all of them including B50, B75, FF, 450, 452X, D97, 8126 and TS1+ for recurves and longbows.
There isn't a "majic" string or string material. Some materials work may better than others but each bow is different. A string material that shoots fast, doesn't stretch and is quiet on one bow may not be the same on another bow.
I've come to prefer D97 especially in a mountain muffler string, 8125 and TS1+.
I can't stand an endless loop string because all I've shot were much louder than flemish strings. All my bows have flemish strings.
