Good luck with your Boushh build. There is some pretty good info here, but I also suggest the Boushh Builders Group & the Bounty Hunters Guild (501st).
I just recently finished my wife's Boushh, which was a length build.
I am working on a belt buckle option at this time. I will keep you posted on what I come up with.
Don't be afraid to ask questions & good luck with your build.
