The 4wt is probably the best all around Fibertouch rod. It is a great casting rod. It is not a nymphing rod but great for dry flies, small and mid size streamers and poppers for warm species.
I have the little brother of it in the 6.5ft 2wt. I have a lot of fun fishing it for bream, small bass and for casting (not dappling) dry flies on mtn streams.
They are overpriced for the components on them but you can find some good deals sometimes on used ones.
Joe C. wrote a good review on the rod a few years ago.
