In terms of value it's pretty fair. But you are asking for 2 specific titles, so you it might be a bit hard to find some who has both, is willing to trade both, and is willing to trade both for a MB. I think you might have better luck if you asked for TAF and had a list of 3-4 other titles around the $3k value you'd be interested in. In my opinion, asking for two specific titles in exchange for one weakens your leverage.
