Re: 1 wt. line DT or WF
Light rods definitely excel with quiet presentation, close-in, so DT lines are my choice. There's another option which I haven't tried yet of using a light rod for panfish in lakes. In that case, particularly since the rod is med-fast action, you might consider a WF to get better distance, but it all depends on what type of fishing you intend to do with the rod, lakes or streams. You can cast a light DT line a pretty good distance so you're not completely limited to roll casting close-in if you go with a DT.
Also, I would not overload the rod unless you've tried casting it with the proper weight line and really think the rod doesn't load properly. You got a 1wt rod after all, might as well give it a chance to cast that quiet 1wt line.
