Juggernaut is right, it is the pro release. The only problem I have is when draggin bottom, or ringing the dinner bell, the line can wrap itself around the pin a few more times, and then won't come off. You have to bring it up with the downrigger. When you get them dialed in, they are a dream. We used snap releases in Elliot bay at first, and the small shakers wouldn't release the line. We drug some of them around for quite awhile, but able to revive them. The nice thing with braid, is when reeled down tight, even if the shaker is not big enough to release the line you can see him on there and release it yourself. What is the perfect setup? Not sure if there is one!!!
