Hi Troy, and welcome to AKFF.
As with any kayak purchase it's recommended to try out a few different models before you commit to a purchase. Finding a kayak that 'feels' right for you, and that you are confident and comfortable paddling is the most important aspect of enjoying your time on the water.
A suitable yak will feel comfortable, will be easy to paddle, will be stable enough for you and will have sufficient storage for all the gear you need to carry and all the fish you'll be bringing home.
What 'works' or doesnt work for other members may not necessarily relate to you. There are many guys here all fishing out of different kayaks. All of them have their good points and some of them have areas where they could be better.
The Cayman looks like a good solid value boat, but you really won't know whether it is right for you until you get your bum in it and have a paddle. While you're there, try and paddle a few other kayaks as well. That's the only way you'll get a good idea and be able to compare. Are there any kayak shops in your area that have test paddle days?
Kayak Fishing is all about having a fun experience...unfortunately choosing a boat that's not quite right can make that experience not so fun. I know youre keen to get out on the water in your yak, but most on this site would recommend to spend some time looking at different yaks before you spend your $$. This is the only way to ensure you get the boat that's right for you.
Good Luck and Good Fishing!
