There’s quite a difference between the 11ft Hardy Avon Supero and the 11ft 6” I have caught barbel on both, but the shorter 1lb tc rod has a much more through action, whereas the 1.3tc longer rod has more backbone in the butt section. I’ve had fish into double figures on the 11ft 6” rod and always felt in control. I didn’t always feel in control with the 11ft version.
For the type of small river fishing I do, the 11ft 6” rod can’t be beaten for me and one of the pair gets almost daily use. Its light in the hand too, and I fish it with Shimano aero 5000 xr and it’s a perfect pairing. Today, that rod landed me my 125th barbel of the season.
