I will be bringing an IPA made with 10# of 2row. Since you warned us the yield was going to be low, I added 2# of 2 row. I usually add 3/4# of sugar to my IPAs to dry them out. I set beersmith to 65% efficiency. I was low about 1/2 a point on my OG. It is dry hopping currently and will be kegged this weekend. I will let you know more in the coming weeks about how it turned out.
My friend Erik, who took the other 10# you gave me will be bringing a NEIPA. His results were similar. I believe he was a point low on his OG. He also added 2# of 2 row and 3/4# of sugar to his.
