You're not over thinking at all, but others may not understand that each individual crankbait swims a little bit differently. Even the same brand, same model, same color, each one can swim differently.
I recently bought a dozen Baby 1 minus crankbaits for an upcoming trip to Canada. I upgraded the hooks on them and took them out and tested them at a local pond. Some of them swam straight as an arrow, some of them needed some tuning and were fine, some of them have that wiggle wart hunting action to them, and some of them just didn't swim well at all. I took a marker and wrote + or Hunt on the good one's, and the dud's got the stock hooks put back on them and thrown into my storage bin.
If you find yourself fishing a lot of crankbaits, I suggest trying this method sometime and you will see exactly what I mean.
