Why two different bittering hop varieties? You're going to boil off any aroma they may provide. Could just use 2 oz of the same one, but that's splitting hairs.

I did think of that and I even thought of just bittering with some Magnum I have on hand... but I'd like to see what difference (if any) that FWH brings to the table aroma and flavor wise vs. just a standard 60 min addition.
