Thank you J Francho, good information which I appreciate.
This past weekend I spent time experimenting with a Super Fluke and various round bend, EWG, weighted and un-weighted hooks, paying close attention to "straightness". All the experiments were on my bait caster which has 30# braid and a swivel to 12# mono. All the configurations I tried resulted in "Barrel Rolling" with a steady retrieve but not with a "pop, pop, pause" retrieve.
I'm pretty confident I now know what action to expect and it was not a rigging error on my part.
