Hallertau and Tettnanger. Mmm, I love thems. Both subtle hops. Great for cheap beers.
Hallers and Tetts are good in wheat beers of all sorts. 55% 2-row, 45% wheat, ~1 oz of Hallers or Tetts per 5 gal.
They're actually pretty good substitutes for each other. I try to stock only one or the other to conserve freezer space and because any recipe that calls for either usually calls for them in limited amounts.
