I have a 5'6" rod that I use for UL fishing. I use that rod more than any other I own. I don't usually cast too far out with it anyway. I use it more to pitch and flip the lures where I want them to go. If I'm going to fish where I really need to cast a long distance, then I use my 6'6" medium action rod.
A lot of it depends on the type of fishing you plan to do.
