Finishing ideas for commission

I have been thinking about what to do at the top of the commission cloak. Trying out ideas by starting the rows.
Firstly just plain. Well sort of plain with the aho cotton (warp) being the same colour as the whenu (weft). The mawhitiwhiti is whale's tail pattern.

Then I tried the twist in brown/orange and black with black aho. 

Now I am wondering if the twist with plain aho might be better. Anybody got any comments? The twist takes a lot of effort but is effective. Is an old technique I have seen on cloaks in museums.
