My Busse's damned sure qualify. I have a good deal of experience tearing stuff up with my Basic 7 and Assault Shaker, and a I'm sure the others will hold up just as well when I get around to pounding on them. My bigger custom Brends also have that feeling about them. I've never taken one out and beat it up, but I'm sure they could stand up to anything I could hand them... I've beaten one of the boot size model 2's all over creation with no trouble.
