Sam, I believe walleyes gain position, flare their gills and inhale their prey even more than bass do. A lot of 'em, even at 2.5 mph, are just suddenly "there"...although some will absolutely annihilate a crank. Once you hook 'em, the larger fish will come in for awhile, then stop and shake their head, come in, stop-n-shake...and if you don't pay attention and play 'em correctly, you'll lose 'em. (Not like locking down and winching in a bass.) Then, of course, when they're 10-12 feet from the boat, no matter what kind of gear you're using, you'd darn well better have your drag set right, because they're taking a power dive and there is no stopping it...
Love 'em.
Here's a quick tip/suggestion...most people bring a walleye aboard with too short a line from the rod tip to the fish, and that's where the problems start--thrashing fish, net troubles, flying hooks and trebles buried in clothing or human flesh. Try to keep no less than a full rod's length of line out at the end, and that'll eliminate a lot of those troubles.
