I started out with 10' rods, then went to a 12' BGJP (which I found to be a bit on the heavy side), then I got a 12' BnM Diamond Series rod and have been using it since. It's much lighter in hand, even with the same reel on it that I had on the BGJP.
I flip double jig rigs when LS fishing (two 1/16oz jigs) and find the longer rod to help in several ways. Besides being able to take up any slack quickly on a long range hookset ( a little more so & quicker than a 10' rod), it also helps to allow me to sit and still be able to flip the jigs over top of the raised platform that my Garmin unit is on. The lighter weight means I can comfortably fish with it all day.
Since I'm just fishing for fun and a few meals now & then, and not for "fame/profit" ... the 12' rod does me proud.
