Galena and Liberty make a fine pils-type beer. Galena and Mt. Hood also works well. Back when I was using those hops in regular rotation, I would often blend Liberty with Mt. Hood for the finishing additions. It helped that I was getting my hops from Mark Garetz during that period and Mark had his hops analyzed for oil content, which made finishing additions much more consistent. I do not know why the big hop brokers do not list oil content on their hops. Alpha acids are useful for bittering additions, but they do not tell one much when it comes to finishing additions.
