To me, custom bait making is about getting baits to work just the way YOU want them - whatever that means. It may be different from what I or Skeeter or anyone else thinks is "right". We aren't the arbiters of "right".... the species of bass in your area of the country, in the water you fish are. We can offer opinions based on our experience and our own biases, or on the opinions others have expressed about particular baits. You have to winnow the wheat from the chaff yourself.
For instance, I build one shallow fat square lipped bait that has a very fast rise. I want to fish it fast through cover, especially rocks, with only the briefest of pauses when it hits obstructions, and the high buoyancy lets me do that, plus it gives the bait more action. Would it spiral if paused long enough to float to the surface? Don't know and don't care because I don't pause it long enough to find out. Skeeter probably wouldn't like this bait. I do because it does what I want it to do when I fish it. Would I also like to fish a shallow bait made to Skeeter's specs? Yes! If a slower presentation would be better on a given day, that's the one I'd want tied on.
