I use it for slower, more vertical presentations. I have eye issues so the brighter line is easier for me to see if there's any slight line tick

My apologies, I should have explained better.
Thinner blades are easier to start up and keep spinning at a slower retrieve. It doesn't mean you can't fish them fast, b/c you can. Picture yourself in a cold water situation? If you want to slow roll in clear water, what would you like in a spinnerbait? For me, I would start out with an easier starting blade, fished as slow as possible making the least noise, yet putting out vibration IF it were a bright day, sun overhead. If slow doesn't work, then speed up. The thin blade allows you to do that. Heavier blades are harder to start up and would need to be retrieved faster to keep moving. Please bear in mind, I'm talking about "like" blades with the exception of the metal thickness.
 
Now, that is a very small part of the rabbit hole to go down in. You know as well as I that a more stream lined blade like a willow will fish faster than a Colorado & Indiana. So all things being equal, a #4 willow will fish faster than a #4 Colorado. What if you took a #5 willow? More mass, slower retrieve and you get the same attributes as a #4 Colorado.
 
If I were to spinnerbait fish as much as I used to, I would concentrate on using a willow blade and worry about cup or crease and how deep cup or crease is. I would also use just smooth blades and use nickel, gold (although brass was my number one) and white. Hammered blades do have a place, I guess.

Basically, a member asks a question...ya know, just like you did. The question would be something like: "Identify this lure" and posts a pic or just asks the question, ya know, just like you did. Usually some member will post the answer and you can tag the post as a "Solved" post, by hitting the "Mark as Solution" next to the "Quote" button...Hence +1. ?

To be honest I would try the large one, but its hard for me to tell based on the pic if it would work or not. Put it on and see if the prop freely spins.
