Default Imperial Porter recipe

Following on the Imperial IPA I just made, I thought an Imperial Porter might be in order. Not really knowing what one of these might be like I have drawn up the following as my shot. Some of my assumptions are based on my thoughts from my Preaching in Hell IIPA and can be found in the posting "Dude of a beer".

I forgot to mention, I am fishing for thoughts and ideas here. The other option is to simply make a boring old porter...

Thoughts of an 8-ish% ABV 100+ IBU brew make my head spin with delight.

WoW! 103 IBU's. That is over the top.
I say you get freaky and dry hop it with some Centennial & Cascade
Or get really zany and use an abbey ale yeast.

Yeh, since I am going into new territory I might as well go all the way.

What looks a little weird to me, and I don't know if this is good, bad, indifferent, or even how common it might be:

This brew has a lot of IBUs; it'll be one bitter mutha. But, it looks like you are just using bittering and aroma hops, no flavoring hops at all. I'm used to seeing high-IBU recipes with lots of hops additions over the boil, this seems a little more unusual in that regard. Like, I know Dude talks about all the attributes he gets from the hops other than just raw bitterness in his Pliny the Bastid.

I don't know, I'm still a noob, so my comments need to be taken with a bit ol' heaping of salt. That's just the one thing that grabs my comparatively uneducated eye.

Check out my other post: http://www.homebrewtalk.com/f12/dude-brew-13424/ This talks about the use of mega hop additions. I am not using them in the middle because I thought I would let a little malt tone come out.

that seems more like it. Porters are my favorite beers, but (IMHO) there are two things that 'ruin' a porter for me. One of those is too many IBUs. The other is too much of a roasted taste. If it gets too roastey, it seems more like a watery stout to me than a proper porter.

But, like I said, this is just the opinion of a porter fan who is still battling to create his Holy Grail Porter.

Holy crap! Nothing like measuring your grain in bags.
