I thought most of the store bought 1/16 heads had #2, but sometime i dont pay attention to the stuff ill never buy. I like to match the hook to the size of body im using. Such as with tubes i like the hook at the base of the body not 1/2 way down the tail. I use slider grubs that are really short and the longer hooks come to close to the tail of the bait and i do not want the hook to diminish the action or cause the tail to tear easier but mostly its that the bait looks visually balanced to my eye. I have some small bodies that i have to use #8 hooks if not the hook would come out the b_tt. Also if im using a jig for bluegill i want a size 8 hook.
