Savage Gear Line Thru 4D Roach 32cm. Our great Line thru roach is back, as a limited edition in 4 great colors in 25 & 32cm. We have adjusted the inner line thru tube, to be 4mm, so that the wire loop can pass thru, both for easy change and for the lure to shoot up the lane away from the fish, during the fight. Also, we have added an Oval split ring, to the modifier, so that the lure can be changed and detached from the rig easily with a split ring plier.
