There's a downside to the C&R tuna-on-fly malarkey, I believe, Nigel - fine and dandy if you are fishing for only small to medium sized fish, but not if there are biggies about, for you will never land the latter on a 12-15-weight fly rod and Tibor Pacific, having to break them off early or kill them during a massively prolonged fight: highly irresponsible and unsporting fishing. Best part of the video, to my mind, was the surface "blitz"ing of baitfish by the tuna - a sight I'd love to see (saw it once, off Malta, when I was sixteen or seventeen), maybe even cast and hook just one and feel its speed and power, then return to watching what is now an increasingly rare spectacle.
