The B17N and the Titanico sound like they are going to be about the same width, which is very cool for you. At least all you have to consider and compare are cut-out, leather firmness, and cost.
From a cost standpoint, $60 for a Brooks vs. $145 for the An-Atomica.... well, I'd go for the Brooks. (but I'm a member of the Brooks Cult!
)
BTW the B17N is $94 at Wallingford. Even if you don't like the Brooks, I'm betting you could sell it for close to what Nashbar is asking on ebay or TE or Craig's.
You might consider contacting Mimitabby. She has Brooks and An-Atomica. One of her Brooks is 30 years old and still going strong.
