mathia14:The thing is HOW hard to hit it?
I get what you're asking and that's where having a specific point of reference will help the communication, even on Skype. The advice so far is sound but it almost seems futile unless you can relate to how the shot strength is achieved, i.e., how much to choke.
With the proliferation of scales-WGT style and homemade style- it's tough to know what one player sees on his scale vs what the other does. There's a relatively easy, built in way to get on the same "choking" page as your advisor-the way the avatar moves in the swing and that little blue piece of ruler at the end of the meter.
We all know the avatar moves in steps. There's one reference. That little blue ruler has 5 places to stop-both edges and 3 lines between them. Another reference. The letter "O" in original right next to that blue box is the first step of the avatar move. That makes 7 specific points you can relate to.
If you want to do it yourself, do the mulligan thing using those points as solid references and mark down what each club does. Play the free unlimited tournies and turn them into practice rounds. Hit into and out of places to try your new knowledge and you'll find yourself mastering those shots in no time. :-)
p.s., A word of caution on trying to be too exact. There are too many variables for 2+2 to = 4 all the time. Get used to playing in ranges, like maybe gimme distances instead of holing out.
