Mr Topes Golf Does Not use Stock Photos. Check out our Item Description below. PING Scottsdale TR putters are named for the true roll they provide as the result of PING’s innovative new variable-depth-groove technology. The grooves in these putters are deepest in the centre and get gradually shallower toward the perimeter to equalise ball speeds for exceptional distance control on putts struck on the centre, heel or toe. An adjustable-length shaft helps optimise performance. Perhaps the only aspect that isn’t exemplary is the putter’s apperance. By no means ugly but I find the simple black mallet design a little bland. There’s a decent alignment aid, however.
