Summary: Last year as a personal retirement investment to myself, I updated my clubs from Mizuno Ti Woods and Liquid Metal Irons to a Cobra driver, Calloway Diablo draw fairway woods (3,5) and Adams IdeaTech a40S irons. The Calloway Diablo draw 3 Wood is a wonderful club.
Summary: Went from some beginner clubs to a set of Ping i3's, realized quickly I was not a Ping guy. Picked up a set of A4OS clubs 3-SW and could not be happier. When I hit it well, its a huge improvement. I am adjusting my distances, as I hit much further with these irons.
