I just bought the Putt 60 Bi-Color Putting Green made by Global Syn Turf.  The contractor installed it last week and the ball rolls so true and fast.  I am a low handicap golfer and want my green to be fast.  The contractor put lots of sand in the putting green turf and rolled it for hours with a lawn roller.  Rolling the green made it so fast.  The contractor shaped the putting green to give me a left break putt, right break putt, uphill putt and a downhill putt.  The color of the Putt 60 Bi-Color is so real and matches the fringe turf so well.  I am so happy I made the investment and plan on enjoying my putting green for years to come.
