for s my jigs i use collar less jig heads like collarless trout jigs this keeps a flat symmetrical body when tied "no lumps or bumps" any ways the problem with the smaller double ring collar jigs is stuff like small 1 inch soft plastics and gulp minnows in 1 inch the ball and ring collar tend to split the gulp and the soft plastics when inserting in to the gulp or soft plastics... this is why i use collarless jig heads. not saying you can use it if your fish like bigger 2 inch plastic you can use it then no problem... any ways i hope this answered your question? i think the crappie down south like bigger baits then up here in Michigan some times...lol's
