haji97071: used full strength, 194 yard hole, 200 yard club full power aimed 20 yards to the left of the pin.
JJ's probably right, you got vemmed. That's still a strong wind for a long iron. That only gives you an 18 foot variance from the water to the hole. Maybe use a hybrid next time and then you'll know you have enough club. It's always better to have to much club than not enough. You get some wiggle room with the meter then.
I've noticed, if you hit ding, or one pixel to the right of ding on a left to right wind, the ball will slice bad, and ding, or one pixel miss short of ding with a wind right to left, the ball will hook just as bad. That's "vemmie".
