I'm not an expert or anything but I would try adding more fat/butter. 2# for 18 lbs of sugar doesn't seem like much. I also make BIG batches of BC at my part time job in a 60 qt mixer and my BC never comes out the same as it does at work.
It depends. If you are doing the carved topsy turvy than WASC might not be sturdy enough. I like to use either a dense chocolate cake or I make WASC and substitute a pound cake mix for one of the regular mixes.
I know there was some classes in MA coming up or recently...one was a class by Maisie Parrish and the other was a class with Bronwen. I can't seem to find the details but I know it was in Worcester MA.
I know!!!! And I am loving Karen Padilla's work too, recently discovered her. I forgot to list my own flickr stream in case anyone want to be my flickr buddy http://www.flickr.com/photos/courtneyscakes/I'd love to know who else here on CC is also on Flickr....
