[/quote've learned that this IEM and wedges requirement typically means that the one using both will be pulling the IEMs out of their ears during the show (and could be multiple times during the show).
I had a lead doing just that because she needed to "hear the band" on stage better - I guess the direct feed was too direct and she was missing the stage/venue sound. This issue was solved by suggesting that she require audience mics on the input list and having them dialed into her IEMs. Once she had these mics dialed in she was more comfortable with the IEM mix and ditched the wedges.
Yep. This!
