The Vienna & Crystal should add some malt to back the hops, which I put in the middle range for balance. If you like your IPA's bitter, then up the Chinook @ 60 to a full 1 oz.
If you like a strong hop nose, then definitely dry hop! I'd suggest more Cascade if you can get some.. Or if you feel adventuresome, use a leftover oz. of Chinook and see how that works out..
I left the Tettnanger out, as that is a German lager aroma hop that just didn't feel like it fit. (Although, I have used german aroma hops in IPAs at the 60-min mark with some decent results
