You can, but it does behave very differently.
 
	 
 
	I've put up a pic of a version I play with to try to avoid Crays wrecking the braided (either coated or uncoated) end section. I call it the JC rig, lol 
	The bead is a tungsten bead, and the slight curve almost gives a claw effect. The hook sits more upright if you have the loop smaller.
 
	It did work, but I couldn't stop crayfish killing real pop-ups, so haven't used it for a while
