By changing the loft sleeve it changes the number of things all you need is one of these wrenches this is standard the face looks nice. And square and ideally it should help you hit dead straight shots however. if you need a bit of help changing the loft is key this time i'm going to put it in higher loft even though there's more loft added the face actually aims more left. And you can hit a big high draw then.
If you lower the loft this time the face sits more to the right even though there's less loft. And really should cause a little low fade i hit this one dead straight then.
The last feature is more upright. And this is great if you hit a slice because the lie angle changes to a more upright language which helps to face aim more left to stop you hitting those horrible slices.
