Has anyone used sunfish (and yep, I know which kinds I can legally use) or perch through the ice as bait? How bout crawfish? I use these all and do well for bass in the open water, so I'm guessing they'll do just fine through the ice. Just starting to stockpile bait, and don't want to waste space of these won't produce as well as other baits. I can catch all of these in nice small sizes.
