I understand the big mouth on the 2 pound plus crappie, I catch my share of them here too, but I just have a different way of thinking about that. First I really believe if you put the color they really want on then they will inhale the jig and the hook gets in close to their throat, Now if they are just not active maybe the lips get hooked a good bit, but when active and you actually hit the color really right on they will end up with that hook way in the back of their mouth and then hook size makes no difference. Now I am really careful when I can see one of my little 1/32 Oz Roadrunners when reeling the fish in because I know it's not in the back of their mouth and then any hard pull may tear it out, but then I figure that would be the same with any hook.
I know you guys average more big fish than we do, but we do catch a lot of 14" to 16" crappie and every once in a while a 17" or even an 18" one. Still I am more a believer in getting the color they want most and if I do I know that jig will not even be seen coming in. At least that is my thinking on that. I do use some #2 Sickles, but even that is a big old hook. All the walleye jig heads I got that are 1/8 all have the #2 Sickles in them and I do even have some #2's and #1's in 1/4, but still mostly personal use I go to the #4 more.
Think about this for a minute and know it shocked me when he told me this, but a guide here on Toledo Bend that use to be the only full time crappie jig here and has his own lodge uses a 1/8 with a #6 regular bend hook, LOL! Now for me even that is just too small, but he swears his customers loose less jigs that way. Personally I don't really care about losing a jig because I have thousands of them so no big deal about that. I guess if I ever porve it to my self that it's better to go big hook I would so guess now I will have to experiment some, but of course my little Roadrunners in spring just have the hook they have so not then. I know with them we hardly loose many fish at all and we do hammer them in spring.
