There's a +1 hcap at my club who I have played with once. He used to be a +2. He had just bought a set of irons, so just went round 9 holes hitting them. No woods in his bag at all. He shot 3 under for the 9 holes. Including dropping a 40ft birdie on the par 4 17th, 466 yards. He hit 3 iron, 3 iron. They really are just focused, and mentally sound.
