Jeff, for me it's not about crack-offs, I use 65lb Power Pro for lures and deadbaiting. why? Because of snags, I used to use 15lb mono until one day I got snagged andleft a whole mackeral and two trebles in the water.
I felt sick because of what might happen if a pike got fouled on one of the hooks and died. I sought advice from a good friend and he advised me to use 65lb braid. Since then I haven't looked back, I've snagged many times, but on a straight pull the hooks have straightened and I've always got the lot back, that goes for lures too.
Does fishing a heavier braid cause you any problems? It doesn't for me and I still play a pike using the clutch/drag, I can't see the problem in using a heavy braid. It's safer and elimantes tackle losses.
