I concentrate on speed. Speed is everything in putting...you can get the line all day long but without the right speed you won't make anything...and even with the proper speed and a line that was just a little off, then you leave easy 2 putts. I line up three balls about 4 feet and roll them...I am looking to gage the speed...I want the ball to get to the hole put not more than a foot past, if they go in great...but that's not important.....once I have that speed I move out to 10 feet and do the same thing...and then finally I will take the three balls and place them a various spots and hit 20-25 footers....with these, I putt them out, because the last thing I want to hear when I walk off the green is the ball going in the cup.
