But that's the only part of mathematical econ that's actually fun.

If you prefer math that gets applied to existing economic systems, look into optimal control theory (pic related). I'd describe it geometrically as "using Hamilton-Jacobi to study foliations of constructed manifolds" (it seems to me that economic intuition is "geometric" in spirit, in contrast to the "algebraic" character of economic mechanisms. Or maybe I'm reading too much into this).
