For accentuating hop profile, calcium sulphate/gypsum is the salt you want to look at. Personally though, while I really like chinook, you won't (in my experience) get much fruitiness or character many associate with hoppiness. It's great for bringing resin to balance fruir - you want fruit to balance the pine. Chinook/cascade, chinook/amarillo, chinook/citra or even chinook/styrian goldings. Combinations and permutations of the above work well.
