Years ago, there was a learning curve for me concerning spinnerbaits. I had to see other guys do well and out fish me several times before I ever started to figure them out. Some things were holding me back. First - proper gear - I was 95% spinning gear guy back then and on the few occasions that I did get bit on spinnerbaits, the gear I was using interfered with the hook set. This got better once I got some early 80's medium of the line spinner bait gear, i.e. a 5'6" MH pistol grip Berkley Lightning rod and a Shimano Custom X 2000 bait caster. That rig had enough tip to throw spinnerbaits accurately and enough spine in the lower 2/3rds of the rod to get a good hook set.
It the time, I was very much focused on light baits, light action gear. That isn't the best gear for spinnerbaits. It is much easier to cast half once spinnerbaits than it is to cast quarter ounce ones and it took me a while to "get " that.
These days, my spinner bait gear is much different. I use 6/8 to 7' MH rods now and Calcutta 200 TEGT reels. I'm picky about spinner bait rods - many MH rods don't have enough tip to cast easily and get the distance/accuracy that I want. Many M action rods are too "whippy for my tastes - so I've picked and chosen lots of different brands over the years.
Currently I have a couple of older All Star 6'8" Zell Rowland spinnerbait rods that I like. I have a 7'Kistler rod labeled as a "small swim bait special" that I like. I have a 6'9" Black Wild Carrot stick rod, which might be the very last one still in working condition - everyone I know who ever had a Black Wild Carrot Stick broke theirs within the first 6 months of ownership. Mine is going on 3 years old now and I caught a 10 pound wiper on it last fall.
When I was fishing tournaments and stuff, years ago, I made a point of looking at what different guys used for spinner bait gear and I was struck by the variety of what worked for different guys. I have one buddy who is way more into spinner baits than I am and he is happy with BPS cranking sticks. I find those way too whippy.
As far as spinnerbaits versus chatter baits, I tend to use them interchangeably, I generally have one of each tied on and switch back and forth. On any given day fish will demonstrate a preference for one over the other, but I can't really quantify why. That's something you have to experiment on and figure out for yourself. Hope this helps.
