still it seems as though the real issue could be spending all that money to get a bike that will be optimized for travel, but still not fit in a regulation case. Of course if B. has given you assurances in that regard, but it didn't sound like it. Personally I would step back from the largely unnecessary Ti up charge and get the real bike that is right for you. Or splash out and get it all. But getting buffaloed into a white elephant with a kludgy take down position at great expense just because there is a sale. That's when my inner voice starts yelling "is there an adult in charge here?"
