We use the droppers and they give great action. The only downside is if you get pitch bait to close to chain. There is nothing worse than having one of the droppers do a loopty loop around your pitch bait line, so I hear......

Used to run lots of cedar chains. Made and sold plenty, too, but no more. Me and the boys like this a lot better. The short length takes up less room in the pattern and there are a lot less tangles than we used to get with the longer chains. We fish 'em anywhere from clipped down in the short holes, all the way back to the long riggers.
For billfishing I prefer to use dropper chains. I run three droppers and two inline with a swivel and something differnet chasing the squids. But don't just add droppers to add droppers. If you really want the best performance then customize and build to suit your boat. figure out where you want to run the dropper. then add the droppers to your chains so the first squid is barely hitting the water, second is jumping in and out and 3rd is mostly skimming the water. then add the two inlines. This will take a little trial and error. Also I have seen lots of mates ad weights to their droppers instead of float or just beads. Poncho on the Prime Time in Venezuela suggested I add weights to my droppers because it will create a bigger splash.
When using in-lines I like lots of squids. Some of the big dogs we fish with prefer inline chains and will measure for the rigger to the water and then will make a chain placing a squid every 12 inches. Makes a pretty long impresive chain.
