Thanks for that offer.Whenever we meet, you are more than welcome to try my kayak, if you can fit in it.
You would probably love how light and playful it feels, but hate the lack of comfort.
I built a 'rolling kayak' based on the Pygmy Arctic Tern with a very low deck, years ago.
My conclusions- Take rolling instruction from a great teacher like Yves Aquin; don't try shortcuts with 'trick' boats!
I sold that boat to another paddler who liked it a lot.
I don't think I could enjoy a very low deck boat for ordinary paddling- I've gotten 'spoiled' over the years since then.
I have an unused set of Black Pearl plans on the shelf.
