I suspect that will depend on the models you have experience of. The 13/15' Prodigy Float isn't especially stiff, it's a pretty standard match (waggler) rod action. The Greys carp rods I owned were pretty mellow for their stated TC and the original Prodigy and X-Flite barbel rods (which I also own) are well known for being quite soft and through actioned for their stated TC. If the newer models are stiffer, it's probably because Greys took heed of the general trend towards less through actioned rods.
