One of the most exciting fights I ever experienced was with a bluefin tuna on a super-light spinning rod. I saw bare spool four times, and each time the line got that low, I managed to gain it back until I beat the bugger. Of course, there are many cases where you just can't play the light game for a number of reason, notably fish health. The best example I can think of is tarpon in Florida's Boca Grande Pass. If you were to use anything other than a telephone pole, you'd never beat a tarpon before the hammerheads ate it.
