I'm the miss the ding putter, straight putts are the only time I would ding it. My stats don't show it, but I'm one putting more often now, usually in the 10-14 putt range for a 9 hole game. At the stage that now, I'm slightly annoyed of missing a putt anything upto 20ft, if the roll is of the green is friendly.
The only time I would move the aimer is when there is a very fast break left or right.
When your close to the flag always hit the reverse view button, it gives you a better idea whare the dots are going... sometimes the dots go in a direction that doesn't show up in the normal view.
If you play a course often enough and land the ball in/or close to the same spot all time you will get to know the rolls, if the pins are in the same spot..... St. Andrews #1 for eg, I like to land the ball behind the hole, when it's at the front of green. The roll of the green never changes and have figured out where to stop the meter..9 outa 10 putts will go in.
Takes a bit of getting use to... but missing the ding has worked for me.
I'm starting to play Oakmont allot now, just for the greens (scores are terrible, but that's another story). If you can handle those evil greens you can putt on any course. It will frustrate the living end outa of ya, but the fast rolls on those greens are good to practice on.
Cheers
