Hi Dustin,
I did not get around to phoning you - lost my phone for a while. Basically, if you put 10 fly fishers in a room on this issue you should get about 11 different opinions. I think over the last decade or so more flies, especially salt water flies, have started migrating to lures. See, for example the pole dancer flies and certain surf candies etc. If it looks like a Rapala, I would say it is no longer a fly, but that is just my view. Tomorrow I will give you another view. In the meantime, if you have serious doubts, deep down in your heart, about your fly, perhaps it is a lure!
