On my last Winnipeg trip, I had great success with the 36" MH Ice Slammer rod: https://sportsmensdirect.com/shop/ice-rods-combos/hwi-ice-slammer-rod/ It's a great value rod at only $12.99 (no need to drop $70-100+ on a custom rod for a trip). I was able to fish both inside & outside using large spoons and rattlebaits and it had not problem pulling up several fish in the 24-28" range over 3 days.
A buddy has a commander, it’s a nice rod. No, you don’t need to spend that kind of money. The Jason Mitchell mackinaw is an excellent off the shelf rod for the lake. Some of the best rods are the quantum rods. Only for sale in Canada. They make a 36” med/hvy that’s fantastic.
Do you have a link of that Quantum you referenced? I know I can't buy it in stores here but I can probably order one from up there.
