If we look again now how the ball is affected by the uphill slope, this slope is exactly the direction that I want to way now, but it is tilted quite a long way up, around about 10 degrees up. Now affectively, the 10 degrees of the slope is additional to the 10 degrees of…sorry, the normal launch angle of my club, so my club might be a 30-degree club on the extra 10 degrees here added on to that, so the ball flight will be far higher than you would normally expect, and you have to understand that a ball that flies high doesn’t always fly further, it might fly up in the air and stall and come down too soon. So although it flies up and it looks lovely, it might not go as far as it was intended because my 7 iron is just going to scoop underneath the ball and knock it too high up into the sky. We also have to consider it quite a windy day, I got a crosswind or a headwind, this ball could really struggle to penetrate the wind and stall on us. So if I hit this one from here, we will see it disappear into the sky and it’s gone far high than my normal 7 iron but maybe not quite as far as it would normally expect to go. It also has a tendency to draw a little bit, that's due to the flatter swing plane and the leaning back swing plane that would pull the ball high to the left-hand side, so we might have to now look at compensations but why the ball flies too high and how and why the ball flies left.
