That's pretty much what I do is follow ASA mechanics, when I work USSSA. The exception is that I'll do the inside 2nd base stance for BU when working USSSA championship play (i.e., state tournaments). Most of the guys I work with in USSSA also work ASA, and when I work with those, it's flawless.

Be careful calling it circus ball by the way. One major USSSA player overheard another "non" USSSA player saying he was tired of circus ball taking over softball...let's just say in USSSA you know who knows the difference between a doctored bat and a normal bat. It's not the rec players that's for sure.
