Red IPA - what do you think?

I was thinking about this today at work (where this and many other sites are blocked).  Would it work to add 1 oz or so each of chocolate, roasted barley, and black patent to the steeping idea?  Would the flavors blend together and be a bit less noticeable or would it end up tasting weird and confusing?  It seems like that would lend the color I desire along with the .4 lbs of C120.  I know at some point I will just decide what to do and go with an idea, but playing with this type of recipe is expensive with all those now hard to find hops!

1.00 oz      Columbus (Tomahawk) [14.00 %]  (60 min)  Hops        17.5 IBU     
1.00 oz      Simcoe [13.00 %]  (20 min)                Hops        9.8 IBU     
1.00 oz      Amarillo Gold [8.50 %]  (10 min)          Hops        3.8 IBU     
1.00 oz      Simcoe [13.00 %]  (10 min)                Hops        5.9 IBU

Where are the 85 IBUs?

I don’t know why Beersmith shows the addtions this way, but this is a partial mash and partial boil, with the 5.5 lbs of DME as a late addition.  I have made a Pliny the Elder clone this way and it came out right.  I agree, it looks screwy compared to my AG full boil recipes, but the outcome is the same.

Something tells me it is an error: 1oz. of Columbus at 60min will give you way more than 17 IBUs.  It looks like 85 IBUs to me.

I find that the total IBUs calculated by Beersmith are generally right, but the individual calculations shown for each hop addition are way off when you are working with a partial mash and partial boil situation.  This recipe when coverted to all grain and a full boil of 8.5 gallons shows a calculated IBU of 121, which seems right.  I don’t even pay attention to the individual hop addition IBU calculation, as long as the total numbers is right, which it has been in the past for both partial mash and AG recipes.  I’m sure the software writer(s) could shed some light on this.

Here is what I ended up with for a recipe.  It has been in primary for 5 weeks, with a 6 day dry hop and is now cold crashed to 33 degrees until Saturday for bottling.  I can’t wait!
