If I am not mistaken, I believe the Mag Bass has SIC guides while the other GLX has recoil guides. If this is the case I would go for the SIC guides if you use braided line. Mag Bass GLX Casting 844C 7' Heavy is the best worm/jig rod I have ever used and it also doubles as a pretty good frog rod also.
Whatever the case, congrats on picking up a great sponsor.
