+1 on the Special B / C120 suggestions.
Love the recipe!
Suggestion for spices. You may want to put some of those in the boil to release the flavors. For 5-gallons..
Nutmeg @ 30min (a little goes a long way.. 0.1 ounces)
Star Anise @ 30min (1 ounce)
Sweet Orange Peel @ 10-15 min (1 ounce)
Vanilla Beans (soak 2-3 beans in a vodka a few days, and pour everything into secondary)
Some comments on the yeast from other brewers, for the White Labs equivilant WLP570.
