What would your choice of yeast be for a pumpkin ale (grain bill http://www.homebrewtalk.com/f76/richards-pumpkin-ale-23489/ ). I have notty, cali V, german ale (wyeast 1007), thames valley (wyeast 1275), pacman or pitch onto a yeast cake cultured from Bells Oberon.
If it were me, I'd go with the thames valley. It should compliment the malt and english hops in that beer really well.
I'm too lazy and have too many beers going to keep updating this!
