The guy at REI said I should get a 240.

I'm 6' tall, and I prefer a 220 cm paddle. Many people are trying
shorter paddles, so try some out before you buy them! I've heard that
some retailers have paddle demo days. We don't have many retailers
around here, so I don't know the in's and out's of it. However, you can
ask a friend if you mind trying their paddle for size.

The eagle and sting ray Aqua Bound have long blades so maybe a 230?

The blades are included in the measurement.
