dpreller -- that seems to be the case, and I figured as much. That said, it looks like more and more people are moving from the general
recommendation for a "textbook" fly rod of a 6-weight, now to a 5-weight, and many now say the 4-weight is the one. Maybe it will be a 3-weight in another 10-20 years.
I just find the heavier line more useful -- just wondered if other people felt the same.
