I second measuring the white balance from where you are shooting. The glass is a different thickness at the ends than on then sides and the light quality will change a lot - especially over the goalies / ends. If you are shooting through openings, get your camera out and the blank replaced before the puck can either damage your camera or deflect and upset the game. The boards will flex A LOT more than you may expect. It depends on the type of game and size of players, but if your hood or lens is directly against the glass, it will shove your camera into your face. Spend a little time getting a feel for how much the boards flex from where you are shooting and be prepared to pull back a few inches - especially in the corners.
