Hop Substitutions for Hopslam Clone

[Morsegeek]

I want to brew a Hopslam clone along the lines of this recipe:http://lancasterhomebrew.com/2010/06/bells-hopslam-clone-recipe/

Both Midwest and Northern Brewer (my local stores) are out of Amarillo and Simcoe. I haven't seen them in stock elsewhere either.

Any recommendations for good substitutions that will maintain the citrus characteristics of Hopslam? Especially crucial for the dry hopping. I was thinking Cascades, possibly, but this is the first recipe I'm improvising and suggestions are welcome.

Rebel Brewer has both but they are expensive. We're talking $3.50 an ounce.

Ahtnum is pretty similar to amarillo, but I don't think anything else out there tastes like simcoe.

Thanks. I ended up finding the Hops I was looking for at Midwest. Their online availability does not match what they have in the store, where they still have Simcoe leaf hops. So, hops crisis averted.
