i will when i have time , actual porcupine quills were the thing at one point in time . the folks i know that used them painted a red or orange ring around them .
but thill and comal and eagle claw and a few others make similar "quill" type floats and or some call them pencil floats .
as mentioned last night on the live presentation ,the slim design allows them to go under the water easier than other designs when a strike occurs .
less resistance to going down is the king when it comes to float pitching for crappie for sure
