"Tactical" probably got focus grouped along with "Competition" and "Euro Nymphing" and won out, but is synonymous.
I like the product lines associated with it. Long, light rods, tungsten beads, barbless curved point hooks, jig hooks. These products are great and I incorporate them readily. I'll fish any given product if it works and gives me pleasure.
The fact that the manufacturers have made a product category out of "Tactical" means they will devote time and money to product development, and that competition will yield more attractive price points. Consumers win. You already see this from lots of tapers in the long rods.
Is it all that different from "Traditional?" No. But it is at least a little bit different, and as far as the products mentioned go, better. You can pay just as much for standard Tiemco hooks as you do for the new styles marketed as "Tactical."
This board often laments the declining interest among younger anglers for fly fishing. These marketers are trying to answer that call. I am going to root for them and reap the rewards not just in new people but in better products.
I have seen far more silly sales pitches than this.
Last point. "Tactical" is even more hyped in non fly fishing tackle these days. Musky and Bass tackle are prime examples.
