What are the ups and downs of using slip bobers for panfish
Use the smallest bobber you can that will stay afloat for the jig or bait you are using. You want the slightest nibble to move the bobber, yet not let the fish 'feel' the resistance from the bobber. Slip bobbers are tricky in the winter unless in a heated shanty or using the one type of bobber where the line passes thru the hole where it is under water. I stopped using them long ago because of the icing problems. Unliess I am crappie fishing with minnows at night on several rods, I use spring bobbers on the end of my rods for gills.
I've switched over to the Venom system. Fantastic!!
