One thing that I was happy about so far with these lures is that this was the first run I tried with the slot on the top method, just for kicks. And I was worried about there being a noticeable line down the top. But without any of the hook hangers in the way, plus some epoxy as a base coat, it easy to sand, and is as smooth as can be (minus the black paint/epoxy issues). The hook hangers on the bottom came out pretty clean as well. It's a bit of a pain, but overall, not tooo much more of a pain than a regular slot method. I think of all the methods, the drill through/fig 8 hook hangers, is still probably my overall favorite. But they all work, and have their merits.
