Hi Nicholas, I use a Futura X5 not Futura X but this works for me so hopefully helps you also. Try lining the Titleist script at your target, instead of the tiny Alignment line. I find it a bit easier to focus on and try to make a right angle between the script and the black line that is parallel to the leading edge. I have heard others who have the Futura X visualise the circle cutout as another ball and align with this, like the Odyssey Two-Ball.
Good luck,
Mark
