Get aero. Get clip on aerobars if you spend a lot of time solo. The OP is so small, even if he's pushing out a constant 4W/kg he's producing about the same power that I average on a Z2 ride. He is at the absolute mercy of the air in front of him.
I often wonder what that would be like-- to get thrown around by a breeze, but be able to shoot up a hill like a missile. I shall never know.
