I use #10 for crappie, bluegill...KY bass...Smallies....everything. Folks think a #10 size hook is too small for crappie....I prefer it. No issues with it whatsoever. As far as setting the hook...I haven't set a hook in years. Due to the jigs and the rods I use the fish hook themselves. If you want to see just how well micro jigs work check out my YouTube channel.....TroutMagnetMan. Whatever micro jig head you choose make sure it is as sharp as you can get.
