For first timers running copper i would never suggest for you to go out and buy a 600' copper. Start with something like 400' or less and learn the ins and outs of copper first. Just like with everything else, there is a learning curve.
Im using fluorocarbon every where i can. Meat rigs, fly leaders, diver leaders, copper leaders, cheaters, downrigger rods, etc. Is it a must? No but the my tournament fishing mentality tells me that if it results in even one or two more fish, every trip out then it is worth every penny. I question anyone who tells you that it is not something that you need. Define need? Do we need line counter reels? No. Do we need down speed? I guess not. But with them we catch more fish. Guys can catch fish using straight mono for sure but they will be out fished by the guys going that extra yard. We all know its stealth abilities. While it may not be invisible, it certainly offers the best solution. I leader with fluoro for "stealth" with spoon rods and also flatlines in skinny water and short cores but I would say the majority of it use is really for durability. Fish after fish, it puts up with beating that mono just wouldnt allow. Its not just fish we have to consider. Charter clients, zebra mussels, nets, tangles, along with an occasional fish help shorten the life of any line. The durability factor is the most apparent in fly leaders and meat rig leaders. Unlike most leaders, these see a lot of direct contact between the fish and the line itself (most of that with a mouthful of teeth). Fluorocarbon's stiffness provides great action to a fly and meat presentation but In my opinion that day when a king has engulfed the hook and is chewing directly on the leader you will be thankful you are fishing fluoro.
my diver setups are exactly the same. Same rods. Same action. Same 30# wire. Same divers (of course on different settings).
If im fishing a shallow high diver then Ill run my slide diver instead.
The action really isnt heavy enough for running divers. A medium heavy or heavy is what you need. They would be ok (not great) for slide divers though.
I went there in August 2013 and fish on the "Predator". Check them out at http://www.mikesmarina.info/. They have a few boats to choose from also. Feel free to contact me and i can probably answer all your questions.

Never had an issue with break offs but the issue is the additional drag with the line dangling in the water. It's works but I'll admit it's not the best setup.

The solterra is a great option for 45# copper with lengths 500 or longer. If the choice is 32# copper then the best option is an okuma clarion 553.
