NSA Rules - ASA differences

[ntxblue]

I'm scheduled to call an NSA fastpitch tournament this weekend. Never called NSA before, but downloaded the rule book from their website. ASA needs to take notice of other organizations sites.

I've been pouring over the rule book preparing for Saturday. Don't like the EP & DH rules, but they are NSA's rules - so that's what I'll call.

Any tips that you can share from your NSA "experience" concerning rules differences that caught you off guard?
