I’ve only iced fished on Sebago three times, and caught the only one that did bite. I was using a rattle spoon that was about 1.5” long with no bait, so it was a rather small lure for the 25” fish but he chased it about 15’ up before smashing it. Just keep reeling/jigging up steady when they chase. Another thing that I’ve seen fish getting caught on are 3-4” plastic minnow baits on jig heads, I’ll be trying my favorite gulp minnows next time I go out.
