Haven't used the others but I can attest to the Maria 'Loaded'.
Very easy to use stickbait; worked it with a KD (definately not the best rod for it but.... ) and it stired the GTs into action amidst E-cups, Realbaits and Delta-5s. That's how easy it is to use.
If used with the ST66 5/0 it will be a sub-surface; wait for it to settle and just crank with a couple of small twitches. Really nice swimming action
I believe a ST66 3/0 is perfect for it but a 4/0 should be minimal for GT applications.
Am gonna stock up on these.
