it seems the selection of DT lines has really narrowed. It is really hard to find them.

What happend? Is everyone fishing and casting long distances now ?

For my trout fishing, I most often fish within 30', and even farther than that my DT is fine. Seems like a WF only helps out the shops and the line manufacturers when you fish like I do. Do you really need a WF line with your 3 weight ?
