Hello Vinny,
I find working with Spinnerbaits is a balancing act where speed (or lack of it) is a big factor. You can use small blades and go fast, or use large blades and go slower. What you don't want is to roll (twist) the bait as it is retrieved, that's indicating to much speed for the combination of weight, blade mass, skirt and trailer mass.
While on the fall the same is true for the rate of decent of any given weight of lure, say for a 3/8 oz lure, a smaller blade will allow it to drop (helicopter) faster than a larger blade; and blade type comes into play as well.
Similarly, a large skirt and trailer can cause a Spinnerbait to become unbalanced and flip over on the fall.
This is something you can experiment with in a swimming pool or a clear lake, use a face mask and get in the water so you can see how the "machine" and all of it's parts operates as it swims or falls (it's a fun thing to do).
Now the question is long arm or short arm?
Good fishin'
