I have fished out of Jackson, perception sport, pelican, and been in just about everyone on there. The KC is the kayak that fits all my needs. I can transport it,hold 2 people, allows me to paddle or trolling motor. I can place 2 45lb batteries in front and go all dam and cover some serious ground if I want. I paddled across the Pensacola Bay, and have done it all. The owners of the company are also local. Diablo is very stable, but same price as KC and holds 100lbs less, and no trolling motor attachment. If you sit in the LOW position in the kc you can paddle pretty quick.
If you strapped for cash, perception sport at academy is pretty good, but NO COMPARISON to KC.
