We have only packed our bikes once, and it is not something I could do alone; however I am totally non-mechanically inclined, I mean seriously impaired. My DH practiced once at home and then did it pretty quickly when we arrived at our destination. Of course, the couplers didn't cost 3k, but they did ramp up the price.
My other bike is carbon, so I wanted steel or ti. Personally, I like the feel of steel, but DH was all for the ti. It does feel smooth. I like both of my bikes, though.
