I'd opt for a DOUBLE paddle and a SINGLE paddle of your choice bent/straight shaft.

I can't speak for everyone here but overall I'd say the "average" paddler in a solo IF they can handle/master the double will be able to go much faster than with a single paddle only ESPECCIALY going INTO the wind and running with it.

Single paddle for cruising/trolling if you fish.
I wouldn't buy a top-line lightweight double paddle unless you've used one before in a kayak and like the way they perform?

People here bought better double paddles, didn't like it and ended up selling them.
