I have tried out the 7.2 for over a year on various practice greens. Finally bought one!!
My club also had a 5.2, and I liked the way it framed the ball, but, if I am honest with myself, I put a much better stroke on the ball with the 7.2.
My favorite thing I have noticed is mis hits with this putter feel different so you know you did it, but actually roll out almost the same amount. Very pleased with my purchase.
