I bought an adjustable paddle made of aluminum and plastic found at most west marine or bass pro shops. With it was able to experiment with best length to use out of the kayak. It was also great for exploring in tight mangrove creeks.
Ended up with a bent shaft ZRE carbon. The bent shaft was too difficult to store on deck. Think about a straight shaft instead for your spare.
