Bittering hop with some spiciness for an American Amber

[petep1980]

My latest amber has a killer flavor to it and came out great. I used cascades all around. It's missing a certain spicey note to the back roof off the mouth I think would really add a lot of complexity.

Can anyone think of a good bittering hop substitute which would properly fit this style I can replace the bittering cascades with?

After reading hop descriptions in beersmith it seems like Cascades is as spicey as I'm going to get.

if you like the effect, Chinook has a spiciness that is quite distinct from Cascade.
