I have a post-ban built from a J&T kit.  After my last trip to the range I decided to add a muzzle brake to keep it from climbing so much during rapid fire.  I started looking and found a bunch of different designs out there.  I'm trying to find out if there are a lot of differences in effectiveness of the various designs, or if most of them perform generally the same and it's more a question of which design would look cooler on the end of the barrel.

Any opinions/experience from you guys is appreciated.

Most that I have read have said that [url=http://www.kurtskustomfirearms.citymax.com/page/page/29585.htm]Kurt's[/url] is about the best.
