Re: WF or DT for 3wt.
Most of the arguments I see for a DT line on a 3 wt. is that you're not casting that far with a 3 wt. That's not the case for me. I routinely need to cast at length with my 3 wt. when fishing. Why do I fish a 3 wt. when I have to fish distance? Because it's more than enough rod for the size of fish I'm catching.
I do have DT 3 wt. line but I use it when I know I'm fishing in a manner that I'm not going to encounter a situation where I need to bomb a cast. I would never overline my 3 wt's and one of the 3 wt's I fish with is a Sage XP. This is just my preference.
