Absolute Crusher annihilator. The Branx pickaxe is both amazing and incredibly frustrating. The melee dance takes some getting use to with this axe, but it's worth it when you learn it. Push -> Heavy -> Heavy is VERY effective, or Heavy -> Light -> Heavy.
Range is really kind of an afterthought in this build. Kickback lets you deal with anything at range that might be a problem, but also won't slow you down.
