We recently ordered several Aqua Bound paddles, the Manta Ray for myself and the Sting Ray in all three editions just to find out which would suit me, my wife and daughter best. They are all great paddles! The Posi-Lock is excellent! I found 75 degree offset my favorite angle. I like everything about these paddles. Even the drip rings work better than the expensive ones I was using before. A sharp edge on the rubber seems to help. Coming from whitewater paddling I like the wider blade on the Manta Ray. Also I did not expect to get free shipping for the box of four paddles! Great deal and service and fast shipping too! Thanks to the folks at Western Canoeing!
