Nice report Joe
The slider rig is my favorite rig to use when Blackfishing as it gives me the most versatility to present my crab. Unfortunately it looks like you experienced it greatest downfall when you hook big fish on the sliding hook especially on lighter leader. The kink you get on leader when reeling in big fish on slider will many times lead to heartbreak as you have experienced. I had it happen 3x on one trip while fishing 60 lb leader. Bumped up to 80 lb leader that day and switched to modified snafu and problem solved. Other drawback of slider rig is if you are fortunate enough to catch world record fish you will be disqualified for having swinging hook.
