Ok,,,, a moderate action rod typically lets the angler feel the rod load deeper into the bend of the rod with the same amount of line out as compared to a stiffer fast action rod. This would be somewhat advantageous when using a DT line where the first 20 - 30 feet of line will weigh less the equivalent length of a WF line.
So if you wish to use a DT line,,, then you may find the moderate action easier to feel the cast compared to a fast action rod with the same line.
