Easy to clean, not many parts can break, great for fishing currents, they keep their value, easy to fish with ( once you get the hang of it ), you can take cool pictures with your reel and fish or just your reel, you can do spin tests to see how long it spins, the odds of becoming a "pinhead" are increased, if you get a really expensive one you'll never be called a loogan, fly fisherman will start to hate you, next to chrome spinners on SUVS the center pin is the second coolest thing, you can really make a womans head turn by the way you run your fingers across the backplate...
All jokes aside, just get the reel, I've never met anyone who got one and didn't like it.
The only disadvantage is during the winter the reel can get very cold.
