I run inline planers, my friend had caught a hog of an eye on one line, only to have the snell snap, the fish had inadvertently from its battle, got intertwined and wrapped up with the neighboring rig which immediately caused that board to sag suggesting to us that he went for that harness as well, lucky for us it was a "cluster" you know what! it was an 8.6 lber.

suggestion: when you tie those snells for your harnesses and you get very busy hammering those eyes, I strongly suggest you use 20lb test or else the odds of your snell's snapping from wear and tear increase.one would have to use at least no.2 hooks, I use no.1 gammies on most and then some 0's.
Most fisherman have a trove of new snells on standby for quick changes in the heat of the battle.
