I'll echo what the others have said regarding the Feelfree series of kayaks with a bit of a caveat. They are great rigs and well built, however, know what you are getting yourself in to with the Feelfree yaks.
Where do you plan to fish most of the time? Lakes or ponds? Perfect. Rivers? Depends on the current. Most fishing kayaks are heavier and wider than traditional recreational kayaks but Feelfree makes some absolute tanks that will give you one heck of a workout trying to paddle against a current or a decent wind. You may see some recreational kayak folks venturing into places you think you can follow because you have a "kayak" also, be careful with that. FeelFree yaks are closer to small jon boats than they are to recreational kayaks as far as maneuverability is concerned.
You can load tons of gear on all of the Feelfree series yaks with storage space rivaling that of a canoe if you pack correctly. However, a canoe it is not so don't get into the mindset of trying to portage a fishing kayak like this.
How will you transport to and from the water? Truck bed? Roof rack? trailer? Realistically assess your physical capabilities when thinking about this. Yes you "can" car top a quality fishing yak but they weigh much more than the 20-30lb sit in recreational kayaks. If you visit some Feelfree forums you'll see that a good chunk of the community invests in trailers for these things because they are heavy. I personally use my truck bed with a strap on kayak cart. I figure I could lug it to the roof rack if I had to but that's not something I would enjoy very much.
Just some things I wish I would have known prior to purchasing mine years ago. In saying that, I absolutely love mine. Stability is second to none, you'll seriously fall out of it before you manage to flip it over. But I'm noticing more and more of the Feelfree community are putting trolling motors on them and after paddling one for years I certainly understand why.
