I know of alot of guys that hate these things, and I too have problems with them every now and then but i have found a "system" that works for me.

First of all you gotta take the thing apart. Then get a nice sharp razor and trim off anything that might hang up the line as you are trying to remove a leader. When you have gotten it "cleaned up", start loading it with leaders, just make certain the first leader you put in, is the last one you take out. I think that is the most important thing in keeping your leader dispenser tangle free.

If you would like, I can take some pics of the way I load and unload my leader dispenser.
