I have been to several seminars where Hank Parker, Jimmy Huston, KVD and Rick Clunn were guest speakers. Rick Clunn always talks about spinnerbaits, the others are pushing their latest sponsors tackle and may or may not include spinnerbaits. I don't believe Clunn has a canned presentation they are all different and when he is at the podium speaking the other pro's are there listening instead of standing in the back visiting.
The last time Clunn was speaking he discussed blades and how he selects them for specific conditions and baitfish. We think of a willow blade for example only by size and color, Clunn selects willow blades based on how fast they spin, how much water they push, how they lift, how they match the baitfish, flash, hammered vs polished, cup, wedge shapes etc, etc. He spent 30 minutes non stop on just willow blades. Details matter.
