When you sasy cut bait, what exactly do you mean? from another perch, or from a squaw fish? sorry if you do not want to share that info openly. Totally understand.
I know in the past i have used a crappie tongue to catch many crappie....very resilient, stays on the hook along time, and for some reason other crappie love it...must be like french kissing or something :)
For cut bait--when i fillet my fish i cut the belly and rib meat out whole. Then i take the fillet knife and re-fillet the rib meat. I use that for my cut bait. I also take the rib/belly meat peices and freeze them to put in my crawdad traps later. Hope this helps.
