Hey Falcon. My first post since moving to Victoria last summer.
I've used spinners for snapper and grouper in Florida, and tuna and yellowtail in Mexico. They've worked great for me but you have to keep in mind what they're good at and what's not so good.
The good is you can cast them a mile, some have incredibly fast retrieve rates, they have a ton of drag, and they won't punish you with a backlash from operator error. On the other hand, they don't have any torque, so you're not going to crank the fish into the boat. You have to use the rod to move the fish.
Also, the really good spinners will cost quite a bit but you can feel the difference. Smooth, vibration-free operation and silky smooth drags are the main differences. I've used mine hard so I invested in a nice Stella and a Daiwa Isla. I have conventional reels too, but each has its purpose. Just another excuse to expand the toy collection.
If you want some pretty in-depth reviews on spinners, check out Alan Hawk's site. It's one of the best:

Hope this helps. Glad to share more as desired.
