Help choosing new yak

[Johnny Hirn]

Hi everybody. I am looking to upgrade kayaks and I have narrowed it down to the Trident 13/15 and the prowler trident. I would be using it for mainly offshore fishing from kelp beds to fishing offshore for yellows and whatever else shows up. My problem is that i cant tell the difference between these two. Which do you think would be better? Are there certain year differeances with quality? Sorry to bother but i have looked all over the web and haven't found the answer i need.
Tight lines,
Johnny

Also I just saw the 4.7 and 4.3 series. Where do those fall in?
Hopefully maybe you guys have tried some if not all of these models and cant lend a hand.
