When you get to the tee on a really long par 5, I know what you're feeling. You want to let the shaft out on the driver and try to bomb it down there. I get the same feeling. But a big tee shot is not always the best strategy, especially on a long hole.
I'm sure you have a hole at your course where you love to hit the tee shot. You can't wait to get up there and bomb away because the fairway is wide, or the hole always plays downwind.
