Dave....you have a rod already, that is capable to 50lb, sell both your BG and TSS4 and get either the Shimano Spheros 14000 or the Salina 80 which I have seen quite a few used on charter boats for jigging and they're going as strong as the Spheros. As for the loooong warranty, I doubt you 'll need it. Otherwise $200-$500 you have quite a few choices.
Shimano Spheros, Twinpower 6000 or the JDM Twinpower 8000PG/HG, the new FE Sustain with technologies based on the new FD Stella, Daiwa Capricorn 4500J is not bad. I have a friend with the Capricorn and the same rod and he did well on GTs to about 15kg... My suggestion is not to buy too many expensive Jap lures and use the money to get a good strong combo, then look at all the other cheaper lures that will probably work just as well. Alternatively you can look for 2nd hand reels.
