70 degrees is the lie angle of most putters. Your putter will travel like it was built to - when you bring the putter off the ground it will travel slightly inside the line, and return squarely to the ball with ease. This is what a "solid" putt feels and looks like.
The 70˚ rail is the most popular plane angle and commonly works best for most golfers.
