Forget those green head gear decoys they dont ride well when its rough. Id go with Herters or G&H , they are spendy but will last you a lifetime.You might find some deasls on them on Ebay. As for decoy rigging for divers the only way to go is longlines Its faster and easier period. Check out Znapz.com for longline snaps they are the best but order some 120 tarred line from a marine supplier for your main line.
