When did you add the hops--all at 60 min? Even if you added at 60 your IBU's will be pretty low (I get around 21-22 in BeerSmith). You might try dry hopping this in the primary after fermentation is complete if you want a little more hop aroma and bitterness. More Cascades would be nice but any of what you listed would be good.
Throw an ounce or more in a sanitized nylon bag (1 gal paint strainers work great and are cheap and easy to find at any hardware/ paint store). You can throw a sanitized stainless steel washer or marbles in there to weight it down and I tie sanitized (unused

) fishing line to the end so I can fish it out after about 7 days.
