If you guys are as insane about "NOT" getting crappie nibbles in the carpet as I am, then here is a little tip to help curb the situation a wee bit. We use tube jigs almost exclusively on both regular jig heads and roadrunners as well. I purchased 2 of the 65ml animal syringes ($1.75ea) from the feed store, trimed off the outer skirt that the needles screw into so that the little nozzle where the fluid exits is exposed.
I fill it with nibbles and place it upside down on my knee and place the tube jig on the end and fill it till it pushes itself off. I can usually go several fish before I need a refill and it sure beats the $25 they want for the name brand screw type injector. Only catch is you need good fresh, soft nibbles or you can rejuvinate some older ones by placing in bowl and add a wee bit of warm water and make a paste.
Works like a champ and they come in a plastic holder you can put them back into when done and keeps things fresh till the next time.
