In Links 2003 it is too easy to putt. I think it is mainly due to the ability to use the grid or the bli to see the exact green slope with little doubt. My suggestion is to replace those tools with two things, an implementation of holding up the putter as a pendulum to see the overall slant of the green, and a light source you can move with the mouse to see the humps and bumps in the green.

I've never got my head around the plumb-bob pendulum method of reading a green, so the above doesn't work for me.
The graphics will determine how easily it s to see the breaks with the naked eye....coupled with the ability to view from different places. In the majority of cases IRL, a golfer will look at putts from 3 generic positions, ball to cup, cup to ball and finally, side on. Those could be default views, e.g. View1, View2 etc. you should ado be able to wander around too. From any of the views you should be able to raise or lower the 'camera'.
