I don't think that hook keepers are all they're cracked up to be. For a large bait they're next to useless. For small(er) baits just thread a small tie-wrap through a split ring of appropriate size then tighten the tie-wrap anywhere you like. Lots use their rod guides for hook keepers but I won't. Guides are made to have line running freely through them, not as an anchor....even the good quality ones are too easy to scratch, bend, etc...
The tie-wrap system works even better if you can put it on your reel without messing anything up.
Some folks with baitcasting rods drill a hole in the fingergrip.
