Funny you brought this up Mr. Kiene.
This was a very recent trip over the border. I hooked a giant jack on topwater that 'almost' spooled me. I chased it down for a bit, and I still couldn't recover all the line it ripped off my reel. My backing was almost all gone so I clamped down on the reel. The fish unfurled the 40-lb bite tippet connection on a Rio tarpon leader. See grainy vid below, wife was chasing me while filming with her phone:

I then went back to the room, made another topwater fly, retied the tarpon leader myself (had the kids yank hard on it so I know the knot was good). Went to the same area and sure enough, got another giant jack on topwater. Only this time, I didn't catch the running line looping over the reel handle as the fish ripped line at a blistering speed.....before I can free up the line, it just freakin exploded. Took my flie, my leader and 70 feet of my fly line.
Saltwater flats fish are scary.
