Kent, I had a similar experience with an H&H 4wt DT. It simply would not load the rod and cast were just falling out of the sky. H&H says if you are not happy to send it back so I did. Last week I ordered one of their new RISE lines in a WF5. I'll see how that works and if it is an improvement over the old olive high floater. The solution to the underweight line was a GPX. If the RISE doesn't work out then another GPX or Rio WF is probably in my future.
