I bought these very cool tip-downs that are spooled and allow for the fish to take out plenty of line with an absolute minimal resistance. I've got them set up for the smaller walleye in my home water which generally run 15"-22" and this set up has been working well for the larger perch as well. I have them spooled with 4lb Fireline Micro Ice Crystal with 6lb Seaguar Fluorocarbon leaders. I'm using red #10 trebles with as small a split shot as I can find. I've been running emeralds (or niagras) under them. I've iced a whole bunch of nice perch and a couple nice walleyes so far. However, these were advertised as being outstanding for Crappie as well (with no specifics as to how to rig them for that specie). I've never specifically targeted Crappie before but I'm about to next weekend. At night with lanterns. So my question is, how might some of you Crappie enthusiasts alter the way I've got these rigged? I'm thinking the only thing I'd change is the hook style and size. Maybe lose the treble and go to a single hook. Also, replace the emeralds with fathead minnows. Any thoughts? Thanks
