I have used both methods from time to time.
It should also be said that putting is my weakness on WGT.
The missed ding to me is just a way to bring in more variables. If you can calculate the distance properly and the direction why bring another variable into putting. I can honestly say that when I line up my putts and stroke them properly they generally go on the line that I have selected. I miss more putts when I line them up and try to compensate for not thinking I have the right line by missing the ding than any other way.
Even on a fairly short putt, inside 15 feet, missing the ding by more than one click can effect the distance. I just think it brings an unnecessary variable into putting. For short putts I generally hit them hard enough to not break and these generally don't need any ding help.
