Senkos are heavy enough to cast with casting gear. I use a medium/heavy or heavy power casting combo to pitch and cast senko and fat ika into heavy cover all of the time. I prefer casting gear in this situation because I'm more accurate casting and pitching into holes and openings and I can set the hook and start cranking quicker which is important to get them up out of the cover. A lot of the time, they bite as soon as it hits the water and I don't want them digging into the weeds. YMMV.
