And here are some wires from my devil guy.

And here's a low poly hand I did a while back ago.

I see that it's dividing the four sided sometimes yes... but I wonder why... that's just making it less clean to look at. But what do you mean with "possible from NGons casuing the patches"? An NGon...

Really? That's strange, since the wire in sub-D should be exactly the same as the polywire with the difference that it's smoothed. So if my model has all quads it shouldn't touch the wire... I mean...

If you have those extra lines that's because you have polygons that aren't 4-sided. If you want a totally "clean" sub-D-model you'll have to have only 4-sided polys.
