First year ump, confused by the number of interpretations of a balk

[Pacedog]

Yeah, it seems like depending upon the league or park you go to and whomever you speak to, a balk isn't always a balk. Parks range from USSSA to Cal Ripken (?) rules. Where to what base a kid can make a feint to and not throw or has to throw. Thought I had it down last week and spoke to a guy who said he's been umping for years and it was totally different from some of the stuff I have read here, read even on the MLB 8.05 rule etc.
