I bought my first GRB paddle several weeks ago, and so far I love it. Weight, balance and general feel are spot on. I have the 12 degree, 50 inches. Great to buy something from a real company/person, as opposed to the 'ships from and sold by da maschine'.
I bought the paddle as a companion to my Zav Z Medium, which I've had for 10 years and is a bit beat up. They are competing for the starting job. The Zav may have to be content with shallow water work.
