Not familiar with White numbering, but WY3787 works great for that style. Might be the same thing.
I have to say that I haven't really enjoyed the blondes I've made with 3787. Of course, I'm not entirely happy with the blonde I just made with Ardennes, either, so maybe it's recipe/process and not yeast. The most recent batch is better than the others, just not where I want it to be.
In general, I'm coming out too dry/ not enough body. I think I need to mash lower or get some DME that doesn't attenuate well (partial mash recipes).
In general, though, I'm a big fan of the Ardennes strain. Whatever the WY number is.
