I found a good article on Bassmaster.com about fine-tuning and making adjustments to spinnerbaits. It’s a quick read, but a good one nonetheless.
Bassmaster.com—Fine-tuning a Spinnerbait
I own a lot of spinnerbaits. Mostly titanium models only because I see a lot of toothy critters and they can ruin a good wire framed spinnerbait in a hurry.
I also keep a fair amount of wire framed spinnerbaits on hand so I can make adjustments to size, blades, and overall profile. I can honestly say, after reading that article, I’ve never put a 10″ plastic worm on a spinnerbait.
