best all around hop for beers that aren't hop forward.

It's hard to go wrong with Fuggles.

Northern Brewer is a really good all-around hop.
Perle is a really nice bittering hop that is often overlooked.
I really like the "noble-type sisters", Crystal, Liberty, Mt. Hood, and Sterling. All are American bred but from noble Hallertaur ancestors. GREAT hops that can be used anywhere you'd go for Hallertaur or another German noblehop.

Willamette is high on my list too.

My question is this what hops do you guys feel cover the widest range of non-hoppy beer styles? EKG seems to be the JZ's favorite based on how often it was used in BCS.

I like Perle, EKG, Liberty and Willamette but I think you can find some overlapping hops like Magnum that work well in both hop bombs and styles with a more subdued hoppiness. I recently made a mild that used very small quantities of a few high alpha American varieties early in the boil that I think is my best mild to date and it doesn't have any of the characteristics that you'd normally associate with hops like CTZ or Apollo.

Palisade is pretty mellow. Dual purpose and blends in with the malt pretty well like willamette or EKG, but has more AA%

I like to add a little Tettnanger late in boil for a touch of hop character for beers that aren't dominated by hops. Just adds a subtle complexity that I enjoy. Any of the noble varieties are good for that. 0.5g/L at flameout works well.
