Typhoon My Alpha irons have Dynamic Gold shafts in them and they are significantly heavier, shorter, and weaker lofted than my graphite shafted Ping Rapture irons. Yet I hit the Alpha irons (C1 Pro) about 1/2 club longer than the Pings. I assume that I'm not able to swing the Pings significantly faster than the Alpha and so the additional weight moves the ball a bit more. Haven't been able to duplicate that with driver though. Even so, I continue to play the Pings as I'm convinced my fingers, wrists, and elbows suffer less post round pain with the graphite - whether it be due to reduced weight or shock.
