176 Soft Ion / 176 KC Pro Roc / 175 KC Pro (11x) Teebird / 163 (Flippy) Pro Destroyer
Very stable mid, stable fairway, flippy distance is the way to be.
Its marked 170, orange, with a blue 2011 worlds stamp. Never thrown, but theres a slight discoloration on the top around the inner side of the rim. It might be storage based.
