Sounds like a LW walleye rod, I’ve built a few for myself. Most important thing for me was starting with a moderate to moderate-fast action. That moderate action keeps them pinned while they’re head shaking at the bottom of the hole trying to get it started up. With all due respect to the walleye lovers on here, they’re wet rags – even big ones. You don’t need a heavy power rod for fighting the fish, but power is based on lure so for active jigging 1/2 oz-3/4 oz baits I’d be going with a medium heavy. I sanded down my own blanks so I can’t help you with commercial options available. I used 48″ carbon blanks from Sportsmen direct, cut a few inches off the tip and sanded it down to make the action more parabolic. That was a few years ago and ice blanks have blown up since then so I’m sure there’s good options now available that don’t need sanding.
If you’re fishing outside in very cold weather then recoils or wire fly guides size 4-6 for runners will make you happy. Handle doesn’t need to be long IMO (4″-6″ rear grip) and I’d put a reel seat on it. I love the Aero style reel seats for fishing with gloves on.
