Were I looking for a bimini for an Angler (and I'm assuming you intend to fish), I would definately get one that can quickly flip forward on to the cabin top as much as possible. I've seen them on larger C-Dorys and I'm sure somebody will respond with a picture of one. Mine (on a Cruiser) doesn't flip forward and that makes landing a fish a bit of a challenge when the bimini is on. The best I've seen has a frame like an L flipped forward. Nothing on the sides to interfere and when flipped back upright is completely out of the way.
The other thing I would have is standing head room. It looks a little odd but it is very nice to stand up and stretch even if it is rainy out. I have side curtains, but I probably would not if fishing was the main goal.
I just looked through my picture album and realized that I don't usually take pictures of my boat. Sometimes the boat is in the picture, but the boat isn't usually the focus (no pun intended). Check out picture #43 in my 2018 Travels folder on Kyoquot Sound. That is what a standing headroom bimini looks like on a 16. On an Angler, it would be 2 feet longer. You can see why mine is left ashore when the fishing gets serious.
