KE is one thing, but what I consider a more important number (espeically in the traditional world) is momentum. Of course thisis weThats one reason traditional shooters pick 600 gr or more arrows. And they are dead quiet. Its probably not possible for us to reach 230fps with a 400gr arrow to equal the momentum of a 650gr arrow going out at 180fps(which is quite likely for a good recurve).

I mean, I guess if one is into that sort of thing, wanting the numbers, nothing wrong with it. But I got to ask, is everyone having issues with 250fps bows? I realize numbers are important and a big selling point in this day and time. And fast is cool. But this is pushing the hairy edge. And maybe counterintuitive for penetration, momentum.
