good call on the ear phones. Every year i see the photographers have been in the pit so i might leave my 70-200 home to save some weight on my back
Definately take you 70 to 200 ... What if you decide to take a few fan pictures off in the distance or you want to shoot scary close *LOL*
A few times I have kicked myself for not taking all of my lenses.Its best to have the right coverage.
