Hi anthony re: sweep - what I mean is instead of building it in 2 separate sections that then necessitates putting in a blend connection piece, you might instead try to build the entire length of the whole final result just as one long sweep with several cross sections in it.

Right now you're building it out of different separate pieces and that then leaves you with the problem of connecting them together smoothing with a transition piece.

If you were instead to build the entire object out of one longer sweep then you could get a shape that was all smooth throughout it without ever having to worry about the continuity of separate surfaces, because you'd have just one long surface instead of several little adjacent ones.

Often times if you want something to have a smooth continuous quality to its shape, it tends to be best to build the whole thing that you want to be smooth out of one big surface instead of building one smaller section of it separately.
