If you examine that same area with the MoI generated model using PaQ's method, it looks like this:





That same area is very nice with this method.

But instead you get the tangent-only area in a different location - where the top plane touches the blends.


I would think the best compromise shape would probably be to do those side blends but only about 3/4 of the way towards the top instead of all the way to the top. Then fill in the remaining area with an N-sided patch or "fill" instead of trying to fill such a larger area with it.
