The Green Flash website says Columbus, Nugget and Amarillo hops. So Columbus is probably in there as a bittering hop. I'd say the 3 oz. of dry hops is a bit much. My inclination is that 3 lbs of Munich too much. I'd suggest 10% of the grain bill maximum is Munich. That is what one would expect for either an American Amber Ale or IPA. I myself would lean to the Crystal 40 to 60 rather than the Crystal 120. Although I would judge the SRM of this beer to be about 14 or15 so that is what I'd shoot for as a target and color with the Crystal malts accordingly to get the color where you want it. Have fun with this.
