Thanks for your insights. I will be seated almost at the very top of the arena so I'm hoping the 70-200 will be long enough. Having second thoughts about bringing the extender, trying to keep the length of the lense as small as possible to avoid any hassles. I plan on trying to balance shooting and watching the game, this is my first hockey game; I have a feeling I will be doing more shooting than watching. Thanks again.
