The new Sustain is improved on all aspects: the blank construction action reel seat and weight.

The new Sustain has features like Hi-Power X blank construction and the Ci4+ reel seat making it a very modern and technically advanced rod.
The Sustain is developed for all-round predator fishing.
The action of the rod is extra fast; this means it's a stiff blank which recovers very fast.
This is an advantage for predator fishing techniques where the angler gives the right action to the lure (twitching jigging jerking).
The rods are designed to be sensitive light and very strong.
The Hi-Power X blank removes blank twist and adds stiffness and a lot of power to the rod.
This provides the angler a lot of control in casting working a lure and fighting a fish.
