Hi All...
If memory serves me, through much of the 90s (or since the "River Runs Through It" movie) there was a lot of writing to the effect that WF was generally superior to DT and it seemed to be motivated by wanting to give newbies the best opportunity to see themselves casting acceptably as quickly as possible. The venders didn't want to miss any recruit with a checkbook because they got discouraged. The WT was just "easier" and, of course, with all the 90s apple sauce about needing to cast from here to Bulgaria, the DT took a backseat because, in untutored hands, it wasn't as easy.
The DT has its' place, or rather a lot of places, but it takes (imho) some experience to really take advantage of the DTs normal characteristics.
I've not heard the Industry is phasing out the DT and it seems hard to think they ever would. But it does seem like they aren't paying much attention to it. Seems like most of the focus is on the WT because it lends itself so well to being produced/marketed with some many taper configurations - something that isn't true of a DT.
Whether all those specialized WF lines actually produce any tangible benefit is highly questionable and each flyboy gets to decide that for themself. I think at least a couple of the special tapers are worthwhile but (imho) there are many that are no better than what might be called a "standard" WF taper.
My personal opinion - it would sure be dumb to quit making DTs altogether, but then, Marketing Depts. have certainly been no strangers to "Dumb".
Best,
