Roger, what are you thinking here? I can't derive a solid answer to that from my own thoughts. Back and elbow, I'm unsure about. Wrist might be easier to figure out??

I didn't mention wrist problems because I personally don't know any anglers with wrist issues (casters or spinners).

However, a high percentage of the elderly anglers I know in Florida, cannot stand and cast for more than a couple hours

without lower back pain. Three gents in particular, blame their years of casting on their back problems,

are all three predominantly use baitcasting tackle. On the other hand, I cast exclusively with spinning tackle,

and though I'm closing in on 70, I will cast for 12 hours if need be without sitting down.

I believe the difference has a lot to do with the difference in the tackle we've been using for the past 50 years.

Although I've used a truckload of revolving-drum tackle in saltwater and live-bait fishing for bass,

I used it for everything "except" casting. That is, drift-fishing, bait-fishing, wire-lining, fishing at anchor, trolling, et al.

Of course, I may well be wrong, but that's why I merely offered this as "Food for thought" (draw your own conclusion).

While spinning is more a flip of the wrist, casting is more of an explosive chopping action (times 1,850,000).

There's another fine Floridian gentleman whose handle is "Avid", and if he get's to read this perhaps he'll chime in.

Don has undergone one or probably two elbow surgeries, and has since switched from casting to spinning.

I could go on, but I'm sure you get the picture by now.

I only use spinning gear and I throw cranks 85% of the time.   It's the tool that works for me and I really suck with bait casting gear.   To each his own and I'm sure the fish could less.

My wrist gets beat up if I'm doing a lot of pitching, but I've got arthritis setting in on them thats a large part of that problem.  Right now, I'm fortunate not to have back or elbow pain and lightweight, balanced rods have helped a ton with the wrists.  

In total agreement with Rolo and I use nothing but spinning, except when trolling or drift fishing in the ocean.

I do get sore elbows on occasion but not from tossing bass gear, only when I'm using a heavier outfit like a 25lb class rod with a 8000 spinning reel.

We have some decent sized bass here in Florida and I never use anything more than a 2000 spinner and a medium rod.
