Not a lot of homebrewers talk about WB-06. I've actually found a lot of info about it over on the probrewer boards. I think there are a couple of issues people run into on the homebrew scale. WB-06 is pretty sensitive to overpitching, and you'll lose a lot of the weizen character if you do. Most of the probrewers pitch about 70% of what they normally would for the volume and gravity. You also shouldn't oxygenate too much when you use it.
I've tried rehydrating, not aerating the wort, and pitching about 3/4 of the slurry into a 5 gallon batch, and I've gotten a lot of the same flavors I get with the Weihenstephan weizen yeasts. WB-06 isn't as good, but it makes a good beer if handled properly.
