There are so many which are successfully used in GT fishing Jason. It depends on how you want to use them, your budget etc.
For fast-sinking types to really have a go at fish which are deep, I would recommend Orion Bigfoot 170 grams and up, and Carpenter Pandora 155+30.
For slow sinking types to work higher in the water column, have a look at:
ASWB SS in various sizes
Orion S-Kiv
Shimano Ocea Pencil 110 gram (a good alternative to the Gunz Tailwalk as they have a similar action but are much better quality)
Heru Bobara
The best of luck.
