2.50 fry~ universal will catch small fish, will catch big fish, pinch the tail your ready to ice fish. Once the tail is off push some marabou in the body and you have a fuzzy grub type bait.
Lead bait would have to be ZV vibrating lure, it would give me a search lure, can be rigged multiple ways, can be fished multiple ways.
I feel with these 2 I can fish both shallow as well as deep. Search for active fish and then once located finesse fish. I can even combine the two and end up with a vibrations tackle style lure.
Last but not least I could take 12" of mono from the rear hook and have the fry as a trailer which would work for trolling
