I don't know how you made it without a computer for two days without suffering withdrawal symptoms. I hope everything else was ok. Not having power really makes a mess of things.
You're on the right track. With a 7 iron, it's all about hitting Down.
Moe was a Swinger. He said that his "Right Arm does nothing".
Hold your Right Palm up with a Bent and Level Wrist.
My typical 7 Iron is 160-165. I can make it go 190.
Ask Tiger if Ambien helps his game. Then watch out for Tasers.
Things get different when you have lower lofted clubs though . . . then it becomes more about maximizing launch conditions and speed. With a 7 iron you can lean the shaft and still have loft left over. The chicks don't hit the driver like the dudes . . . so it is about "talent" to a large extent . . . just like Mikey Jordan got the hops . . . and Bubba can bust it 400 yards . . . ain't no chicks sniffin' on that jumping or thumping drivers.
