I know nothing about your specific bow, but I suspect that your string is too long. Just twist it up some more and shoot it. Keep adjusting the brace ht till it shoots straight and quiet. If you can't twist is that far, try a shorter string. Remember, the mfgr's suggested brace ht it just that...a suggestion. As you don't seem to be tapping into anyone with data on the bow, just shoot it and determine for yourself what is right.
