Hey VooDoo,
I run a very similar boat. Most days I prefer a 6 rod setup to keep things simple. 2 riggers, 2 wire dipsey divers, and 2 copper/lead core setups (I will run 4 on calmer days) You can run the coppers/leadcores off your TX44's, I personally use a planer board mast and big jon otter boats. I would def get yourself a copper setup. Your 7 color will get you down 38-40 foot, so a 300 copper would be a good choice (~down 66ft @2.5mph). You will need a 45/55 size convector (or equivalent) reel for the copper. As per your Diver setups.....I'm not sure you can get 1000ft of wire on a 20size reel, everybody i know uses 30's. Also those fresh spring kings at the bar can be absolutely violent, most guys will tell you Magda pros wont last.
I'm no where near as experienced as some of the guys on this forum, but it if you would like more info I would be happy to help through PM.
