I think CRT sells the A&A brake..... Or did. I don't think he has one he made himself. I might be wrong, but I don't think so.
I ran the Griner brake for years and liked it. Any of them work good.
Have heard nothing but great stuff about Protrans. If I was to buy one today, would probably try one of his.
