keep in mind that if your goal is to have the same mouth feel and balance as an IPA with a light (1.040-) beer you need to add some non-fermentables some way (higher mash temp) to achieve this. if you want bone dry beer (nothing wrong with that) then don't worry about it
I agree, you need to keep some body. I'm tempted to use 100% 2-row and mash a little higher than normal.
I just did a 100% 2-row ale. Starting gravity came out a little higher than expected - 1.047 - with 25 IBUs and finished with 1oz of Crystal at 20 and another 1oz at flameout. Used S-05 and it finished at 1.011. I thought it was excellent, and it proved to be a very popular beer with friends and family. So I figure why not try something similar with say Cascades or Amarillo?
