Your family had good tastes. RS is a kick ass game.

Since you are interested in a mint IJ I'm guessing cost is not a problem. I'll just repeat what others have said and go with the fast/flow angle. AFM or SM would be my choice. For budget JM is a fast monster.

If you're a widebody fan I would strongly suggest checking out DM. Don't let Sly's fat head scare you away. It is a blast. I almost passed on mine, but now I'm surprised how much I like it. You get the best of both worlds. A fast, flowing widebody. You won't get a particularly deep ruleset, but you've already got that covered with your other titles. Also, it gets far more play from the casual players at my place for some reason.
