I know where you're coming from with the frustration of Unity, but don't give up... I was at the point of giving up until CF was available, but now I have accepted that Unity is your 'broad brush' tool for giving the course it's flavour, and CF is where the detailed work will be done on the actual golf related areas... I'm using the time until CF is available to 'prep' as many terrains as I can so that I can be in a much better position to do the 'golf bits' when I have the tool...
Stick with it
