My kayak is like 70+ lbs. It is still fast, carries a lot of weight etc.
I look at the accend kayaks and they are super stable and slower. Many people complain about weight. I seem them as boats more than kayaks.
I get that many people want them. I listed pro's and cons. For me, this direction is just more involved that was simpler kayak fishing was/is.
I have seen it, performed it... I get my kayak out, rigged, and paddled off faster than a lot of the other ones, even pedal drive. Getting back out, I am also fast. Get home, I would then hoist it up on my paitio ceiling using a pully system. That was when I lived in a condo. Now I own a house and I just put it in the back.
Finally, looking over the years, a lot of the fun was rigging it up. Cutting and running things. Now all is done and people are afraid of their kayaks. This the same in all industries though. No real slight, just the costs of innovation.
I have GAS, GEAR ACQUISITION SYNDROME. I am always looking for something. When I see these kayaks, I like them, but I see more limitations for some of my personal application.
As you said, thankfully we all have a wide variety to select from. In the end it gets us all fishing. All because it is not my cup of tea does not mean it is not good for others or the industry. Their direction is just where I chose to stay or course or turn away, however you want to see it. We all get to some water to fish.
