Like JMR40, I have had a Tarpon 120 for 3-4 years now. I originally wanted the 10' but they didn't have it in stock and I am impatient.
I have fished some rivers, but mostly small lakes (300-500 acres). I put a fish finder, rod holders, etc on it. Been using a drift sock lately and what a game changer.
I think the hardest part for me at first was trying to cast sitting down with your legs out. I also use much shorter rods now in the kayak, I find it easier to land fish.
Don't skimp on a paddle either. They can get pricey, but IMO worth it if you are going out all day or any kind of distance.
