Another vote for 3522. It and 3787 are my favorite Belgian yeasts, hands down.
The dry Belgian yeasts are okay, and I keep them in stock when I am not sure when I am going to get a chance to brew. But they aren't as good as 3787 and 3522.
I recently split a batch between 3787 and 1388 (Duvel) yeast. 1388 is pretty nice if you want restrained phenolics, but I definitely preferred the 3787 version with it's fruity esters.
