JMO but you are comparing two different types of kayaks, sort of a large touring car vs small car (say cadallic vs scion). Paddle 1/2 mile of open water (ie chop on the water), fish, then turn around and head into the wind for the 1/2 mile return trip. You'll quickly appreciate the extra length (and associated speed). Also keep in mind that in the Cuda, you can stand up and fish, not so much in the d10. In the Jackson lineup, the Daytripper is a more similar model to the d10.
