Like its name suggests, the Double Action works two ways; set the hook with a long sweep of the rod or let the fish
bury the pole and hook themselves. All hooks have a super-wide gap and a barb on the shank.
Size:
Just finished the Clear Lake, Ca. fishing Derby. Caught 8 fish that I weighed with biggest being 15.6lb. I caught 7 of them on the 5/0 hook. Only lost one fish and that was on a Kahle Hook.
I was pessimistic about the shape of these hooks but, don't let it fool you. Put your rod in the rod holder, when it's bent over double, just start reeling. None of that nibble nibble, jerk like crazy back on your rod. Seriously, just start reeling. It's That easy. (I came in 23rd place in the tourney!)
