Those are commonly known as knuckle buster or knuckle duster reels, depending on who you talk to. One of my good buds does all his salmon trolling with one and has landed lots of nice kings up to 35lbs on them. (although his brother landed a 50 plus at la push :shock: )They let you feel the fish better( some say), but you lose the mechanical advantage of a star drag levelwind type reel. So one turn equals one turn on the reel instead of three or four that you get with a star drag, which can make it tough if the fish is running straight towards you. I believe if memory serves, that you can't just keep reeling in when the fish is running, so they take a little more finesse. I also believe they are more popular in canada than down here. I have fought one ten lb blackmouth on a knuckle buster, and it was pretty fun. I have been wanting to get one sometime but haven't gotten around to it as you need a rod that will balance that type of reel. And yes just like most fly reels you can change one model to right or left retreive. Where with a star drag you have to choose right or left retreive. And can not switch it. Man am I jonesing to go fishing!!
