I pull cranks 90% of the time from my kayak. I use 15 Lb. braid Fireline with a barrel swivel to a 4'-6' fluorocarbon leader of either 8 or 10 Lb. with a coastlock snap to make changing baits easier. The heavier leader keeps bass or cats from breaking the line. I used to run mono, but lost too many fish once the line got saturated and became more stretchy. I also changed out all the hooks on my cranks to Gamakatsu hooks, just because they're sharp enough to catch if a fish looks at it too hard.

I think the ebb and surge of paddling makes the cranks dart slightly because the power of the stroke isn't constant like what a trolling or gas motor delivers. Since the braid doesn't stretch, that energy transfers to the lure. With mono, the stretch absorbed some of that stroke surge and the lures ran more of a constant depth & rhythm. Either way catches fish, but I lose fewer fish on braid and fewer spit the hook on the way to the boat than with mono. I have to stop paddling most of the time to play a fish. I had to use a more forgiving drag setting to keep bigger fish from pulling lose, but I rarely lose a lure that way either.

This is what works for me. Everybody has their own system & preferences.
