One additional thing to consider on the line is line management. Here are a couple thoughts I have on the subject.
Personally I have not had good luck with the bluewater type lines from RIO. I have had the Leviathon and Deep Sea lines. I have found the running line core to be very stiff and have a lot of memory. This made it tough to get the line to shoot through the guides cleanly when you need it the most. To that end I have had the best success with traditional lines that have more tradtional cores. I may learn to regret it one day but if you can land 200lb tuna on 20lb tippet why the need for the 65lb core? Like Sean said I have been using his RIO Outbound with good success. I understand they don't make that line anymore so I am also looking around for a substitute. I like the SA Clear Tip line but they only go up to 13wt so I am not sure if it will load the TFO Bluewater HD.
I use a basket to store the line between pods but not during the actual presentation to the fish. Keep some water in the basket to help keep the running line lubricated so it won't stick to itself and tangle. However, don't try and put it back in the basket when you are presenting to the fish. Strip the line onto the deck so you can concentrate on getting tight to the fly and making the right retrieve.
Not line management related but I think it will prove usefull if you are new to casting the big rods. When making your back cast lock the rod butt against your forearm. This will help give you the leverage you need to power the cast. These are big rods with heavy lines and you will get tired in my experience.
