I flop about 90% of shots that are on the 60ft putting scaleor in the fringe. I am deadly from 9-19 yards flopping...and yes I do it often on the greens. I flop because Ican almost guarantee Iwill be inside 4ft, and more times than not, I have a chance for it to go in. For me its a lot more consistant, aleast the way i hit it, than chipping.
As far as for the topic...yeah...scale option should be added....maybe even telescoping :).
