One thing which changed in the almost 10yrs since this thread was last posted was Vais going out of business. Sadly so, they were a very good break.
What may have also changed considerably in the 10yrs is the selection and availablity of suppressors. I don't recall more than two or three locations in Kansas which had them available in 2008, whereas there are probably a half dozen shops just on the close aide of Wichita to me which sell them now. While they might not break recoil quite as much as a rearward directing brake, the reduction is substantial, and the noise reduction is even moreso. If the HPA passes, my son might never know what an non-suppressed centerfire rifle even sounds like.
