I think if you make a two panel, the bottom panel should have somewhat of a ridged insert or a bit more ridged bottom panel so you can use it as more of a seat to provide some structure when sitting but not so stiff it becomes uncomfortable. I have one of those Notch Floating D saddles and I really find it super comfortable because that bottom panel almost acts like kind of a seat but its not so ridged that it doesn't "Form" around your butt. I'm not really a sitter but I'm finding myself doing that more in this Notch because of that feature. Then you move it up the back a little when leaning, it really is a way to make a saddle multipurpose. You hear so much that this saddle is more for a sitter and this one is more for a leaner, why not have a saddle that affords you to do both.
