SPRO Fluoro Leaders. A 10" single-strand fluorocarbon leader for muskie and pike fishing. Per 2. Available: 80 lb., 50 lb. with power swivels or ball bearing swivels.
I have become a believer in these leaders for Pike. At first i was skeptical, but they work great. They will last 2-3 days each, compared to steel leaders that only last a few fish.
Used these on a recent Canada Trip - I was one of the few in the group which did not have a leader or snap related failure. I found the snaps very difficult to use so I switched the cross lock snap which came with the leader with a duo lock snap which worked much easier. I used both the 80 and 50 lb test leader and had no problems with either one.
Lost some nice Northern Pike and lures due to the leader comming apart in a short amount of time. The ends of the leaders are of good quality, so I cut hem off and made my own.
