Bentstick81, I sympathize with your problem. Just a story from my perspective. I have two longbows which get my continual use, both have straight limbs and handles. Both are supposed to have a brace height of 6 1/2" thereabouts. When I noticed that slapping sound you are talking about and/or vibration in one of the bows, I set to getting rid of it by increasing the brace height enough to get rid of that sound and because one longbow backs the other on my hunting trips, I set them both the same. It completely eliminated the noise from one bow, however, to make the other bow's noise disappear, I also had to change my grip a bit by moving my bow hand around a bit and making sure to keep the elbow bent. As long as I do that, both bows are quiet. I think it comes down to what you can make work for you, particularly if the arrows are flying true and the only glitch is the noise. I don't think it will take much of an adjustment. In my case. I have to wear the bracer and as you have identified that is where the noise comes from it's just a matter of making that small adjustment to keep the string from any contact with the arm, regardless whether you wear a bracer or not. As long as that string is contacting your forearm, there will be noise.
