For Alto, I find that the Classique responds much better than any Vandoren BlueBox I've tried. The colour is very similar, but more rich and vibrant. BBs on alto have just been plain stuffy to me, which isn't a great way to achieve tonal "darkness". The same pretty much goes for Vandoren BBs on Tenor as well. On Tenor, I prefer Hemke reeds for concert. The Classiques have issues on my mp of choice, being that the facing is quite long and the Classiques are too thick near the vamp to accomodate this (thus they leak near the table) On clarinet, the BB Vandorens are once again, stuffy and nonresponsive. The V12s are much better for me. Personally I just don't like the BB reeds as a mainly classical player. There are just a lot of other, better reeds. Some made by Vandoren themselves.
