I grew up in ASA but have emersed myself in the NCAA signals for the past few seasons. I typically use my NCAA 'hammer' for everything unless my tournament UIC specifically requests that we use the ASA signals. We do not have any formal HS training here, mostly ASA umpires applying the NFCA rules, so I can't speak to their signals/mechanics.

My opinion, ASA developed signals and mechanics that are simple and can be broken down into steps as trained in their schools and clinics because they have to be able to teach anybody how to look like an umpire. The NCAA, at the national level, umpires being evaluated for post-season and D-I assignments, requires a more 'professional' signal. I like the look of the NCAA 'hammer' and I think it looks stronger than the ASA signal, but I agree with Mike that some people can be too aggressive with it.
