Not that great myself, but found out thru experiment that after you left click and hold the mouse button down, roll the mouse upward to get full power. You'll see it go up on the indicator bar. when you have the amount of power you want, stop and relaeas the mouse button... but be ready to click it when the bar moves to the right and gets to the center mark between the other left and right marks on the indicator bar. If you click too soon, you'll top the ball off the tee or fairway and go left, if you click too late, you'll take a divot and lose the drive distance as well as go right off the tee. Good luck, it takes a bit of practice before you get the hang of it... once you do, you'll keep getting better the more you play! Can I add you as a friend to play a round sometime???
