I've been using the Yo-Zuri Pink fluoro 100 lb leader for bottom fishing here in NE FL. I build a leader using two swivels and a 10oz sliding egg sinker. I snell the 9.0 or 10.0 circle hook on and have a pretty reliable rig. I fish for grouper, snapper or any large bottom fish, but occasionally hook into large sharks. This leader is supper tough but still relatively easy to crimp or tie. Love it!
