If you go there I have a picture of my Mudkat Line Guide. If you don't have a Slotted Retriever it has no purpose. I only own that reel and a bunch of parts I take with me. It keeps the line from falling out the side of the reel when a fish takes off or after you shoot. Just makes life easier.
AMS does not offer their reels with 200lb dacron for some reason, but since they get so many complaints and 400 is so popular they orref it with that for more money. Well worth it though. That reel in the picture has the 500lb Power Pro and that reel is going on 17 years old and good as new.
