audible suggestions???

okay so recently ive switched from ATL's PB to NE PB and ive had great success with it the only thing is that i dont have any audibles like i run the plays and i havent needed to audible too much so i havent put any in so i was wondering if ya'll had any suggestions? it seems like such a waste not to use my audible options but when i try i just cant think of certain plays to put in that i would need to audible down to. any help on the matter would be appreciated.
