I'm going to share with you all a technique I picked up the other day from another angler. I haven't seen anything like it yet nor have I seen anyone else discussing it on here. My local lake has had a trend of bass suspending around 15-16 ft in deep water (deep water is relative, in my case it was 40-50 ft.) I came across a guy dropshotting in the deep water with success, and my curiosity peaked. He showed me his rig which looked like a standard drop shot, until I noticed this guy was running 30 ft of tag end for the weight. What he would do, was setup his DS rig with about 3 ft of tag line, then attach a small swivel. He then took what looked to be a 1/2 oz DS weight and attach it to a spool of line, guesstimated how much he needed to reach the bottom to below the suspended fish, and attach it to the swivel. I asked him about this, and he said the swivel allowed for quick change of depth without having to retie a whole rig. Of course, I had to ask what he would do if he wanted to cast away from the boat instead of a completely vertical presentation. he then proceeded to flip the bail on his reel, grab the tag line about 4 ft from the weight, and sling it by hand as far as he could throw it, engaging the reel once his weight hit bottom.
It was a little unconventional, but he was catching fish when most others where getting skunked.
