I shoot a A&H 64" #54 @28 14" riser standard grip. The grip is not for everyone, but it fits and work's for me, as for being quiet I have a D-97 12 stran string with bow jack's, everyone tells me it's quiet I think so. They are fast! But what I find about it more than being fast is it cast a arrow pretty flat out to about 35 yards.
(485gr)as for speed I have a couple of custom bows that are just as fast ( Morrison and a Gerlock) same specs. I shoot split finger, as far as cut past center call A&H. You really need to shoot one before you buy, good luck.
