I am currently rowing Sawyer oars (9') and considering trying Cataract oars. I have no complaints with the wood oars, they have good feel, but I could use a little more "bite" in the water I think. Is anyone out there using Carlisles or have suggestions about the Cataract blades-regular or magnum. I am thinking of going with the SGG shaft and magnum blades assuming the regular blades come with the oars at Sportco. Any info or advise is appreciated.
