The Shimano Aero Quiver is an excellent rod for small river fishing for roach and chub and as Matt says, it has a lovely through action. I still use mine for winter fishing on the Upper Witham.
An even better rod for fishing on small rivers for roach is the Drennan IM8 Bomb Rod, the original 10ft version. This is a very sensitive quiver rod that shows the slightest of bites, which roach are often well known for on those cold winter days.
