I'm doing a 10 gal batch of APA and I thought I had 6 oz of Centennial on hand but I guess I mis-read some Cascade and I only have 4. 
Any suggestions to make up the missing 2 oz?  I have Cascade, Amarillo, Willamette, some British and some Noble hops. 

My recipe was 2 oz at 60, 2 at 15 and 2 at flame out.  I'm sure I could use Cascade instead but what else would partner well with the Centennial?  Or should I just use 2 oz of Northern Brewer at 60 since I doubt you can taste them at that time?

If I was to sub in Amarillo instead, would you suggest using them at 15 or at flameout?  Or combining them?

All those options sound good.  The northern brewer would certainly work.  Cascade and Amarillo are great as aroma additions, but so is centennial.  I like willamette with centennial, but I really like fuggles too so that's just me.  You could always split the 15 & 2 min additions with 1 ounce of cen and 1 ounce of your choice.

Any of those options could work, the theme should be fruit and flowers.  Adding earthiness and spicy aromas/flavors gunks it up.

Another option would be to do:
60 min:  2 oz Centennial
15 min:  1 oz Centennial, 1 oz Cascade and/or Amarillo
0 min:    1 oz Centennial, 1 oz Cascade and/or Amarillo
I often add them after the IC has chilled the wort below 180F (the flashpoint for many hop oils) and let it steep for 30-40 minutes.

I'd skip the Willamette, British, and Nobles for an APA.

I use equal parts Centennial and Willamette for the late hopping in Ambers and Browns. Great combo IMHO.

In an APA, though, I'd probably go with the Amarillo. Unless you're hoarding it.

Use the Amarillo as a substitute for your Flavor & Aroma additions of Centennial.
I just did something similar.
It's "knock your socks off" delicious.

Yes, every day I go down to the freezer, gaze lovingly at my 4 ounces of Amarillo and laugh maniacly how I've got the market cornered

I'm leaning towards 50/50 Centennial/Amarillo as some have mentioned.  I did a brew with only Amarillo for flavour and aroma and I didn't like it as much as my APA with straight Centennial for both.  But, it was a different grain bill to so I can't say I did an apples to apples comparison.
