The Staff D300 are irons that from a distance standpoint can compete with any game-improvement competitor on the market. In terms of distance, FLX Face technology is the driving force, as 76 percent of the clubface is not connected to the body of the clubhead, which allows for more flexing at impact and faster ball speeds.
