You can't go wrong with WY1388 or WLP570 (also Duvel). A recent golden strong my brother made turned out quite well with 570, it had a nice fruitiness it that definitely is reminiscent of Duvel. I bottled a golden strong last Tuesday that I fermented with WLP545, which is reportedly from Huyghe (Delirium Tremens, etc.). I haven't tried the final bottled conditioned product, and there seems to be a lot fruit in the aroma (bananas maybe) and some spiciness, which is the yeast character was I shooting for. As for a favorite? I think may stick with WLP545 because I like the ester profile and it seems to ferment well. After two and a half weeks my beer went from 1.085 to 1.008 and finished with (a very smooth) 10.3% ABV.
