VEXpro 2015 Product line launch

Regarding the new 1/2" hex VersaHub, is the new one just smaller and lighter and less expensive or is there something more meaningfully different?

If I recall, on the old ones the hex was not consistently clocked relative to the bolt pattern, so it wasn't possible to use two of them on one wheel. Instead you'd need to use one plus a hex bearing held in place with screws. I'm hoping this is what is different and the new ones, so that two can be used on a wheel and the hex flats all line up.
