I am really trying to be a fan of the new "head on a stick" articulation. It sounds really neat in theory, it looks a little wonky at the jawline of most of the figures, but it does give the heads more posablitity.
The deal-sealer ought to be the ease of popping off the heads. The Clone Wars Asajj Ventress figure was able to have a nice removable cloak thanks to the feature. Dagobah Luke actually comes with two heads to make use of the easy head-pop.
But why for the love of all that's holy does every neck post need to be a different size?
I tried to play around this afternoon with some simple stuff--Dagobah Luke's head on VOTC Han and vice-versa, but the necks are two different sizes and the results are awkward. So I tried Ozzel, yet a third size. So I tried Dagobah Yoda. He's actually pretty close to Ozzel, but why in the world would I want Yoda to be wearing an Imperial Admiral Uniform (unless he's in disguise..?)
Way to go Hasbro. One step forward, two steps back.
