after running a bar for a while I found that size was important but not nearly as having a good head on their shoulders. With today's legal environment you really have to be careful with your guys beating up on customers. I like having my guys with enough size to make you think twice if you wanted to tangle but my guys were expressly instructed that the priority was removing the problem not beating it. My bouncers did a lot of labor in the place and were not just muscle. Consequently I was less likely to hire a guy with a high level of training that seemed to want to bounce for the confrontation. Quite often my guys found it was easier to explain that you can leave or they can throw you out and then you can go to jail.
