Looks like a yummy brew...however, I'd change the hop additions a bit:
1oz Cascade (60m)
1oz Cascade (15m)
1oz Liberty (5m)
At the advice of others here on the board, I've ditched the 30 minute hop addition and moved it to 15 minutes. I increase the bittering hops to make up for the lost IBUs, but get a more flavorful and aromatic brew.
