Free,

That's a super good deal on a awesome set of oars. Oversize shipping alone from OR is expensive.

Curious, why do you think you got the wrong length?

I'm running 9.5's Square Tops in place of 9' Cats and love them. Best piece of kit on my boat. They are so much better balanced and have a much greater usable ship area than any other oar I've used. Before you wish you had them back, I'd check with the guys at Sawyer, if you haven't already. They're great guys and know of what they speak.
