????? Recommendations on my next PM brew - 10 GALLONS Brown Ale

Howdy,

I am trying to get as close as I can to a (partial mash) Downtown Brown by Lost Coast in Eureka, and add a few adjuncts here & there.  If you see something out of line, or have any suggestions, they are welcomed and appreciated!!
Also, by viewing this, I was going to use about 3-4 gals for 60 minutes @ 150 for the grains.  



Thanks in advance, Dill
