Creating larger body flies can be a pain depending on how much dubbing you need. The time consuming and monotonous part was always twisting a dubbing loop. I knew there had to be an easier way. I started googling dubbing tools and I ran across this video. It showed how to use a dubbing twister tool. I bought one of these and I can tell you they work awesome.
There are basically two different styles of this tool. The cheap one shown above and a slightly more expensive twister tool shown below. I can see the one below being more efficient if you are tying a lot of flies. For me the simple tool works fine.
