Nice write up! Mind sharing the recipe you used? And why the special roast? I agree that the beer has a roasty taste, but always found special roast more tangy tasting than anything, though that may just be me.
Here was my brew. looks easier to read if your column width is big enough to prevent wrap around. I lost a bit more than ususal since I didn't use hop sacks. Ended up probably about 9 gallons finished beer. Gave some to a friend.

I made an appropriately sized starter.
My FG was 1.017 (ABV 7.3%)
per BeerSmith 21.8 SRM, but seems to be darker in the glass - this has been a problem for me since I switched to Beersmith. Maybe I need to get some SRM cards to compare to my computer screen. I have no clue what my Special B SRM contribution was, as it seems the different suppliers can have quite a range. I wish homebrew suppliers were more diligent about informing us who the maltsters are and what the SRM/L values are.
I steeped the aroma hops post boil, and I had actually cooled the wort to around 140ºF before adding them, and I let them sit for 30 minutes. I think that I will probably maybe just knock the temp down to 180 next time I try this. I'd been reading the volatile hop oils have some low flash points which is why I tried 140, but I think i didn't extract the aroma and flavor that I might have had with just a flame out addition like I've been used to doing.
I couldn't tell you if the ahthanum hops added any significant effect or not, but as I had them on hand, I used them.
I would also point out that I think my hops were off in the side by side, because of 1.) lack of vigorous boil with decreased extraction/utilization and 2.) steeping hops added at lower than traditional temp.
I added the special roast to try and capture the roasted flavor that I think is in there. I will probably skip the Special B and Special Roast altogether and try toasting a portion of the C-150, and possibly adding just a tiny pinch of roasted barley. I might try tasting the crystal malt beforehand to see if I can discern any plum or roasted notes that I think I taste in the commercial AB.
I've rambled enough already...
