For one, Tiger Woods doesn't even have a 100 mph swing speed with a 7 iron.
If you would have said 100mph swing with a driver (longer club meaning more speed) I might believe you, but considering you're age and height I really doubt you swing a driver that fast...and if you do swing that hard with a driver, there is absolutely no reason for it. You would have no control over your swing.
I learned a golf tip a long time ago and I've learned a lot from it. It's not how far, it's how many.
