I have no idea what the modern drennan feeder rods are like but I have an older drennan feeder rod, it's a 12ft im8 super feeder and it can cope with much more than the line ratings and casting weights stated on the blank , even the im6 light feeder is up to much more than stated....if you want to push them that is.
At one time (and even now) a lot of anglers who frequented Ireland for the bream fishing swore by the im8 feeder rods for distance casting on the large waters over there, my friend uses his for barbel on some quite large rivers and has no prob's casting heavy feeders or reaching his desired ploppin in spot
