string angle on top of box

I am thinking about the string angle on the top of the box on my latest build.

My thinking is that the steeper the angle behind the bridge the harder the bridge presses onto the top of the box. The bridge must push down hard enough to get the most sound out of the top but not so hard that is starts to suppress the sound, this is also dependent on the thickness of the top and such.

 Anybody got any thoughts on this, I know the Banjo crowd consider this a deal breaker, but I do not know how it translates to acoustic CBG's. Must be the same with resos to "drive" the cone just right without squishing it to much so it only squeaks.
