If this is true, then the reason why plastic lines have a larger
diameter [than silk lines] is the fact that fishermen prefer their
lines care free.

Chas Bingo!

:-)

Chas Personally, I don't have any trouble casting a modern 3wt DT in
Chas a wind, so I don't see any reason to bother trying to push the
Chas square peg of a modern line into the round hole of a silk line.

Well, for me that seems to depend on the length of the cast. For
example, while fishing with my 2wt last week, I was having plenty of
trouble with the sidewind when trying to reach feeding fish that were
further away. (I can't give you any exact measures of the distance I
was or was not able to handle.)

I am aware that a 2wt is not a long-distance tool, but since I
couldn't wade there, and the fish were surface feeding, and _did_ take
the fly when I was able to cast it there...
