I'm paddling a FS12, or the "angler" version of the D12. I've been real impressed with this yak, and here's why...
First of all, the seat rocks. It's super comfy and for exceeds any other kayak seat I've sat in, bar none. Stability on the kayak is good enough to stand with a little practice, but I don't stand and fish. I'm just not looking to take a swim while fishing. Storage is pretty darn good, and I love having the premolded crate/5gallon bucket space behind the seat. I use a crate with rod holders screwed on to store my gear. I really dig the seat, the pre-molded paddle notches and the adjustable footrests are back savers. Somebody at Bass Pro really put some thought into this thing.
There are a few things to keep in mind.... If I had it to do over again, I'd buy the D12 instead of the FS12. I ended up buying scotty rod holders and throwing away the factory rod holders, because they weren't very good. Also, the anchor trolley got replaced because it was cheap plastic stuff. I kept some of the bungees, but for the most part, the only thing I kept from the "angler package" was the paint job. Save yourself the 100 bucks and rig it how you want it.
Some minuses.... kayak is HEAVY. I'm a big guy, but a 12 ft long kayak that weighs 80+ lbs fully loaded is hard for me to carry. I'd buy or build a kayak cart if you plan to unload/load this thing on your own. I don't use one, but I sure wish I did sometimes. Also, like I said.. the ascend fishing pole holders and anchor trolley are pretty much garbage. Get quality stuff. I think I spent 30bucks on rod holders and 10 bucks on parts for my trolley. Also, this kayak doesn't have a compatible rudder system. If you want one, you'll have to kludge something together. Fine for me, that's what I do anyway.
I really like the D12.
