Now more similar to wood blades? I'm not quite sure what that means in the sense that Butterfly has not really changed the basic concept behind most of their ALC blades in almost 20 years. True a really old TBS or Viscaria is not exactly identical to one you buy now, but the differences are relatively minor in the overall scheme of things, and actually the oldest ones were a bit thinner, slower, and more flexible, and therefore more wood-like than one you would buy today.
Perhaps it means that with these heavy and larger diameter plastic balls, the various ALC blades (or their ZLC various cousins) basically give you the same overall power relative to the ball that one would have had with something like a Clipper or Cresail back when we could speed glue Bryce and were playing with 38 mm balls? It sort of seems that way.
One thing I am quite sure of, back when I first came back to the game after a long layoff, there were quite a few carbon blades, but when people I talked to thought about carbon they figured it meant something like a Sardius or a Gergeley, or something like that, and weren't thinking about the much more controllable ALC blades. So a lot of good players from those days (well actually they are still good players) advised me to avoid them. At the time I bought my first Viscaria (this was before the emergence of ZJK and was around 2007 or so) it was a somewhat obscure blade, the only reason I found out about it is I hit with a clubmate's blade (and that evening ordered two of them). Actually the first carbon blade I ever had was something from Tibhar, it has a lot of balsa in it I can't remember what it was called but I am confident that if I tried it now I would think it was awful. (Maybe it was a Rapid Carbon, did they make those in ~2000?). Before Viscaria, I tried all sorts of things, never really actually played with blades that I know now in retrospect would have been good. I probably should have been using a Clipper in those days or a Korbel. One blade I remember that I had was a Nittaku Narcus. It was a bit Korbel-ish I think but with a ridiculously small handle. I had a Keyshot for awhile, that was really nice, but that was just before the Viscaria.
