Do u use through-wire design? I just thought of this so it may be a really stupid idea. With the bait cut in half, u could drill a small hole in the lip that lines up with a small drilled hole u make on each side in the lip slot of the balsa. Put a tiny lead shot, bb, tiny pin crossways or what have you in the lip hole, insert the lip/bb in the lip slot (along with your epoxy), and put your two sides back together. The lip won't be able to pull out because it will be anchored in the bait head. Depending on how heavy your anchor choice is, u may have to adjust your weighting a hair to counterbalance to your liking. I am 1000 miles from being an engineering genius like some of the fine fellows on this site so if this idea is idiotic, I apologize.
