I decided to take upon the task of fishing both with and without a trap hook and WOW!
With trap hook
5 brown rockfish
3 sculpin
1 HUGE octopus
0 lizard fish
Here are two pics of some of the big hits that I missed on the single hook setup
Here's a pic of the ONLY fish that was landed on a single (circle) hook. And just so that no one gets the impression that I'm for some reason I'm submitting the same fish even though I've caught and weighed most if not all of my fish in front of others I'll start submitting pics of the underside showing the gaff shot.
