+1 to FM - perfect explanation!
jayw4862:What you say makes perfect sense, but I just wouldn't think it would be that bad on even lies.
It's Even Lies which makes it bad!
Imagine taking this shot IRL: the clubhead's arc would point uphill, using the ground as a tangente. I love to do such shots with a wood - it's like rocket starting the ball due to the additional loft.
Here, with Even Lies, the clubhead moves "on even ground", but the ground rises in front of the ball. It's like a trench for the clubhead with an end close to the ball position, and you must worry to overcome it.
For once, the Even Lie is a wee disadvantage.
