+1 - Last year I did a Bo Pils for the comp season. I was a bit iffy on the AA% of the Saaz I was using so I slipped in a bit of Magnum as insurance. It wasn't a lot, only around 15g and whamm - far too bitter <_<
So I tricked it up with some very late Hallertau and it was reborn as a German Pils and won a trophy B)
Now I'm very conservative with the Magnum (mine is German Magnum). Apparently GER Magnum is the second biggest grown hop there after the Hallertau Mittelfreuh "family" so I reckon it must be a favourite for Pils bittering, as I experienced myself.
Galena here. 60 minute boil and there's a tiny hint of berries, but it's tiny.
But in general ... the most neutral bittering hops are almost always the high AA% hops, simply because you use less of them. Some hops break this rule though - the big NZ hops come to mind.
Another thing a bit OT - have you ever noticed that the higher the AA%, the yellower the hop pellets? Saaz and Hallertau are dark greeny-blue, Galaxy is limey-yellow.
