There are a few options around for a really heavy chugging rod. You could look at:
Ripple Fisher 78XH (quite a bit stronger than the 79H)
Patriot Black Mafia
Carpenter SP78UHL
Sevenseas Bigpop 78 Powerful
Fisherman 77 R10L
Before you go down this path though, I think you should think about whether you really want a PE12 rod. PE12 is brutal and realistically for 95% of us, I think we'd be better of stopping at PE10 (130lb). In addition, PE12 will not cast as well as PE10, a rather significant issue. Considering that you're really leaving yourself the option of using Varivas GT PE12 or rope, it is a very expensive limited use outfit.
This time of outfit is really for limited use where you're in the type of location where you need this type of super heavyweight gear. It really is not that comfortable to fish with. As Duncan sets out below, it's not an "all day" rod.
Brad, if you're expecting a GT78XH to be very similar to a PF, I can tell you it isn't. The XH is brutally strong and while it will be a dream to pop big chuggers, it will not be a dream 10 minutes into a big GT.
