Rockfish, Joe, has done it in darters before and I think Frech did in his darters too

Never been a fan of epoxied sealed plugs but I might give it a try on smaller stuff. I got a small spook (zara style) from Ted that shamed stuff I made in a similar size out of basswood with minimal amount of lead.

I think it certainly helps the buoyancy with smaller stuff.
