I use an AquaBound Manta Ray Hybrid on my Ride 115, but I'm 6'4" and I like a big blade. You should be using something around 220-230 cm. Check out a Bending Branches Angler Classic. Reasonably light with the fiberglass shaft, and the blade design is very good without being too big.
Werner makes some very good paddles, also.
Dad took me fishing when I was 10, and I've been pretty much hooked since. He went to be with God on August 14, 2012. I miss you, Dad.
