slimjym: Does it make any difference whether we change the position of the box/triangle to aim our ball, while I assume, clicking on the swing meter dead center, or is my method of clicking an appropriate amount left or right of dead center just as good?
I'm putting off-ding, too - it was so simple as a noob. Alas, I regret it, I missed a lot of practice in Ding putting, too much to change now. Now I am a medicre off-ding putter :(
Common to both is that you must hit with a certain strength and click at a certain point to get the putt in.
The biggest difference is that the putting strength drops if you click far off the ding. So, you never really know how hard you putt. Big plus to Ding putting.
Other fact is that you can't hit enough off-ding on severe slopes on slippery greens. Then (about at Tour Master) you must move the marker - why not practice it all the time before?
One related issue is that some putters are good for dinging and some are good for off-dinging. Forgiveness is the key, look before you buy!
