Malibu Kayak Help

[WildernessWanker]

I currently have a Hobie Revo 13 which I absolutely love but I always have a secondary yak to take a friend, to take out when I want to paddle, or to take out when the conditions are going to be super sloppy. I had a Tarpon but recently discovered when I opened the garage unit it was in that it had been stolen. So time to involuntarily shop around for another yak and thought I'd try something different. I love the idea of storage as I like to store as much as possible below deck to cover any possible chaos on the water and to help with surf launching/landing wherever I want without losing gear. I have heard nothing but great things about the Prowler 15 but like the storage options of the Malibu line a little better. My issue would be with all the different yaks in the Malibu line: X-factor, X13, Stealth, X-caliber, eXtreme, eXpress. I understand some of the small differences such as the bait tank of the Stealth, storage of the x-factor, etc... but can anyone offer up pros and cons in regards to outfitting and/or fishing any of these models. If it helps I'm looking at buying used so if there was a feature on a certain year please mention it to make my search criteria more specific. Thank you in advance for any input!
