I have an unopened Cooper's Lager extract that came with a kit they sent me that I'd love to trade for another extract kit or even a finished wheat beer if anyone was interested. I've done this lager before, and would just prefer to brew something else a little more challenging.
Nice..I think you'll enjoy the propane feature. Most important part of smoking is temp control. Low and slow will provide you the best results. A great site for smoking meat is http://amazingribs.com
Have you tried this with the American Wheat and British Ale yeast? I'm thinking of brewing a batch of this in a few weeks. Just figured I'd check to see if you had nailed this recipe yet :)
