Nice noodle you got there! I'd just be kinda nervous handling it for a little while since I've heard the bite from this guys are pretty bad.
Are you going to keep your eyes out for another one at NARBC?
GTP's are the ones with the big teeth. I think that may be what youre thinking. ATB's stay much smaller i think and dont have as big teeth. ATB's only get to 2-3feet and stay slender whereas GTP's can get up to like 6ft i believe.
