If I'm gonna be tying up roe bags and only partially paying attention to the rod, I put the reel on freespool and turn on the clicker. When I'm done tying up bags, engage the drag for a faster hookset.
My set up in a Penn 330 with an Amundson Sturgeon/ Shimano Technium (just about the same rods). My line is 150lbs Power Pro. I thread the line through two big plastic beads, through the eye of a 20kg snap swivel, then two more plastic beads and tie to a 80kg swivel (I use a polamar knot here). I take a 36" length of 96lbs sturgeon leader (dacron) then tie an egg-loop on a 8/0 Gammy covering most of the shank with the egg loop. I tighten the knot by grabbing the tag end with pliars, and wrapping the leader around my sleeve. The knot should be rock hard and should be impossible to spin on the shank without using pliars. Tie the other end of the leader to the 80kg swivel with a knot that is a bit like a clinch knot, but meant for braids.
NOTE: you're not going to be able to pinch the barb on a 8/0 Gammy without snapping it and leaving a faux-barb, so I take a Dremel to that stub and grind it down completely.
Clip on a weight onto the snap of the 30kg swivel so that if you snag your weight, you'll just spend 10 seconds clipping on a new $7 weight, instead of 5 minutes trying up a new rig.
