Eels - how big is too big?

[JohnR]

Personally, I like eels between 12 and 15 inches with a little girth too them. Beyond that, it can get tough not to mention the ability of the eel not do what you want. I've caught them on larger eels but it's not the type of eels I want to use. One thing I'd recommend, get black eels - they work the best...
