I have had good success on big bass, bulging just under the surface, a Single Colorado blade black skirt, short arm spinnerbait, and I don't fish at night. Same bait slowly crawled on the bottom catches big ones two. I know a longer arm bait has more vibration, but an old short arm scorpion doesn't want to role over when waking the bait, and has caught me big bass for years.
I like full Lumaflex skirts with no trailer. Trailer doesn't hurt, but not using one is my one and only chance to really make the Monkey mad.
I like to bend the wire at the head of the spinnerbait up causing the body of the bait to run more horizontal in the water.
Blades that are half one color and half another, work well, when I can't decide what color I like
One gold one silver blade works well.
Colored blades work well on cloudy days, and dirty water. Colored blades work well on sunny days and clear water.
Pink and chartreuse blades are not just for smallmouth.
Mag Willow blades also called Oklahoma blades are very versatile.
A bullet weight placed ahead of a spinnerbait is an easy way to get the bait deeper, taking the rubber core out of a rubber core sinker, and crimping the sinker to the hook is also a good way to get a spinnerbait deeper.
Contrasting colored skirts work well. Chart black, White black, orange black, Chartreuse blue, and two of my oddball favorites purple chartreuse pink black.
All white is boring but works in any conditions.
If a certain color of jig, soft plastic, or crankbait is working, that is the color of spinnerbait I will try first.
Big spinnerbaits with big blades slow rolled deep get big bites.
Stanley makes the best willow blades, Hildebrandt make the best Colorado blades, Fishermen's Shack has the best selection of Magnum Willow blades. That's my story and I'm sticking to it.
I'm not convinced thin wire is better, but I do fish both thick and thin.
I prefer closed loop, but R bend is easier to keep tuned.
I don't care about the color of the head, if I'm fishing a spinnerbait correctly the paint is chipped off after a day anyway.
Inline spinners will kill a skunk, and may catch a PB.
