As far as I know there's just not a lot of information out there on these tiny strings. Shrew bows have come with a 6-strand 450+ for some time, and that was considered "tiny"--but it's almost twice as big as a 4 strand Dynaflight '97.

O.L. Adcock has done quite a bit of testing, but mainly with his bows--different bows can act a lot differently as far as noise, speed, stability, etc. Might gain a couple of fps, might gain more. Might get a quieter bow, might not. Might be stable, might not. The only way to know for sure is to try one and see how it works for you. I'm not in any hurry to try one on my bow, because it's fast, quiet, and stable with 14 strands of Dynaflight--and I have a good supply of arrows already matched to it. When I get a new bow, I'll probably tinker some.
