Sounds like you're making an English IPA: it's quite common to use 3 oz Fuggles for this recipe. Dry hopping doesn't add too much bittering, but can add some grassy aromas. How about just seeing how this batch turns out as a traditional EIPA, and then try another batch with dry hopping. That way you can see which YOU prefer.
On Tap: Barleywine, Coffee Oatmeal Imperial Stout (big big beer)

"One of the first things early caveman did, when he crawled out of the mudd, was to make beer. And cavemen everywhere are still making beer...and drinking beer." - Jean Sheperd
