I've done it from the trees before. As you say it's no different to any club. Just follows the usual rule that higher lofted clubs tend to curve less than lower lifted ones.
Do you have a standard shape Itchy, and if so how often do you try and play shots with the opposite shape in a round?
Yeah exactly, and its usually an option to go over the obstacle if ive got a wedge in my hand anyway.
Nautral shape changes for round to round, im normally pretty much straight, but i set up to hit it both ways at different times especially off the tee. Id say im more likely to hit a fade if i just aim to hit it straight though, and i find it easier to hit a big cut than a hook i think.
