I have their Ridge Supple Impact taper on several reels, from 5 to 8 weight. The Impact, I believe, is more of a bullet-head design than the Tactical taper, but I'm sure it behaves the same. Love the Ridge design as opposed to the SA Sharkskin; you can see the ridges on the smaller (2-4) wt lines, but on the larger ones it's nearly invisible.
It's far and away the limpest, least kinky line I've ever used. Like a soft cotton twine in your hand. A great casting and shooting line, but, as DL says above, not the best floater in the world. I use it for indicator fishing in FW and for throwing streamers and such in shallow SW flats, so I don't particularly care if the tip sinks a bit. So I guess it depends on your intended use.
Ebay has some great deals going on Airflo Ridge lines right now.
