CK, with Winter Run Steelhead that's more the norm than the exception. Majority of those fish appear to be in the 12-(maybe) 18 pound range and they can strip line off your reel like a freight train run a muck.
All be it several years back hooked 'the big one' with not much more than 60-70 foot of Carron Line and leader off my reel. Within 10-15 seconds the balance of that 150 foot of line and another 50 -75 yards of 30# backing were gone. Had to stick my (thank God for a heavy coat) arm between the rod and out going line and see if I could turn him.
I'd like to say I landed that Puppy ... but no.

But at least I didn't get 'spooled.')
