I have been using droppers from Hali for a few years, with good results. Also using the ones from ProScandanavia, which are short, but have clips at both ends, which allows you to pick the hook size, and style. Custom Jigs and Spins has a dropper spoon, which can be easily adjusted directly on your main line. I tend to use this set up more for perch. Experiment, be flexible, have fun!
