one of the things I have found with wire, is on berkely, the crimps will show apropriate wire size ,but even with these, i have found out tha you got through with the wire, back through, and back through again, there is room, and it leaves a bump just before the crimp, and cannot possiblly pull through, I know guys use crimps on flouro, but I have always been afraid, the crimp might cut the material, so I tie, even if I put splitshot on flouro, i crimp it lightly maybe burr on sinker, but I also use 20# flouro
