You bet. I always work with two rods when fishing for sunfish. One is rigged with one of my homemade slip-float quills, the other is rigged with a down shot rig. Some days and some situations one will work better than the other. The kid in me always likes the quill bite better.
I used them a lot in my younger years while chasing crappie! Loved em. I mainly fish for White Bass,Fresh Water Reds,Catfish,and Striped Bass. Very rarely do I use a float now. When I do use them it's a slip float!
