Hi Booleano, what about if instead of making the neck bottom a straight piece, if you instead made it a sweep that curved downwards at the end like this:



Then if it is trimmed by a side profile you'd get this kind of shape:





And also if the sides were extended up like this:



Then it could fill more space up and get trimmed down:





So you'd be getting this kind of larger trimmed surface instead of a patchwork of separate pieces:



Then the tricky part becomes adjusting the shape of the sweep so that it comes close to the end profile that you want since the end profile is formed by a trim rather than drawn in directly.

Does that seem like it's better or not?
