The main arugment for a DT that I can think of is that you can turn it around after chewing up one end, so essentially you can buy half as many lines. That being said, here in Kansas the wind is usually blowing hard enough to twist your ears, so a DT is a pain. I’ve been using all WF since I got here. When I get back to Arkansas and spend more time on the little Ozark streams chasing smallmouth fifteen feet away, I’ll have at least a couple of DTs again. For now though, WF is the way to go up here.
As for brands, it’s not stylish, but the Cabela’s Prestige works well without being too overspecialized. It is a screaming bright color though. If you are after a sinking line, they have a couple of No Vis options avaliable.
