When fishing spinnerbaits, crankbaits, etc. I'm old school and use a right handed baitcaster, so I cast with my right hand then switch the rod to my left hand. But I started using left handed reels about 15 years ago when I was flipping/pitching or fishing slow moving baits like worms and bass jigs. I pitch/flip/cast with my right hand and reel with my left. This felt better to me as I used to do a lot of jig fishing for walleyes with a spinning reel, so holding the rod with my right hand felt more "natural" when working these other baits.
