My $.02 is to take a legal bull when you get the chance and do not wait for a huge 6x6 like you see on TV. TV shows often show guys passing on bulls and ending up with a monster later in the show. First time elk hunters usually tell me that they will hold out for a 6x6 ("even a smaller 6x6 will do - I'm not picky").
My goal was to shoot a bigger bull than I have shot before, or a nice meat bull. If you have never shot one before that sets the bar fairly low.
