I am using all the hinge actions with my irons,with much success.To use the dual horizontal hinge action with the driver is another story.Every time I open the driver up I get weird things happening.The course I play at has irons only driving range,so i don't get to practice the big dog.I used to play a draw with the driver but it would start down the target line and then turn over.The irons I play are 2 degrees flat so I don't hook the ball.
Any suggestions? I play a 460cc driver.
