The VENN doesn't come in a 2.25. (I wish it did!) Do you mean the 2.0? Somewhat surprisingly, I find myself leaning more toward the VENN now too. (The improved version, not the original.) I've experimented with the American Cut on alto for a while, and although I enjoy the reed's responsiveness, I think it's a little too bright for classical playing, even in the 2.75 and 3.0 strengths I've tested. I think you can use the AC for concert band, depending on the type of music, and obviously it would be great for a marching band or anything with electric instruments, but if your individual tone is going to be seriously scrutinized, you'll probably want something more refined. But the VENN seems nice and dark even on a Selmer Concept or Yanagisawa AC150, both of which are lively, colorful classical mouthpieces. The reed's ridiculously overhard strength profile and the lack of quarter-strengths means that the only VENN I'm completely comfortable with is the 2.0, but it's not bad.
I like the VENN's simple plastic reed sleeve better as well. The new giant Legere reed case takes up too much space and is too hard to use; it feels as though I'm risking the tip of the reed every time I try to pry it out of the case. And the amount of plastic involved is distressing for a disposable item.
