I am aware that many people advise beginners to use WF lines, I have just
never been able to figure out why. I rather suspect it is because there is
more money to be earned on a WF line, and advertising is a very powerful
force.

I've always suspected the same, due to the fact that a well cared for DT will
last me 6 years of pretty heavy fishing, while a WF only gets 3. The economics
for the line manufacturers seems to dictate the marketing strategy. For normal
stream fishing, I have never seen where a WF line conveyed any advantage, even
on some of the larger streams I fish. Admittedly, I mainly fish for trout and
smallmouth bass in streams from 10-100 feet wide, so my practice wouldn't
dictate anyone elses choice.

What you need to do is go fishing and enjoy yourself, that is really what
fishing is all about.
And that is the best advice of all!
