If you are looking for a "fun" FS and were thinking a spearfish, I'd suggest checking out a horsethief? 120mm travel bike, "A very capable climber, Horsethief does have a slight bias toward descending, letting you enjoy the fruits of your uphill labor. By designing the bike for use with a shorter than normal stem, the body is positioned better for aggressive riding."
From what I've read it's a lot more fun to ride, just doesn't climb quite the same. (Which doesn't matter if you aren't racing.) They have a Medium on closeout at Rochester Bike Shop, and if I had the $$$, I'd be considering it right now.
