Hey Ben,
I have a GT Special and I really like it. The cost does not break the bank and the rod is quite capable of handling large GTs. I use mine with an 18k and 100lb powerpro. The only drawback is that it is a heavy rod. Team it with a 20k and there is going to be one tired angler at the end of the day. I have been doing research on the kaibutsu rods, I have a long cast version with a 10k and it is nice and light. I just recently shortened the butt section as it was too long for me. It appears that the other kaibutsu rods have the same long butt section. So, unless you are rather tall, it could be a problem for you. It was for me.
