Hi flux100,
While I don’t have any personal experience with their vZone … I can tell you that zoning can make a difference with body types that are more difficult to “fit”. The advantage of the zoning system they use is that it can be customized to each person because each person is unique in their body type and sleeping positions and the type of zoning that can be most beneficial to them.
You can see some general comments about zoning in this article and in post #11 here.
As you know … FloBeds is a member here and I think highly of the quality and design of their mattresses and the service and guidance they provide to their customers.
Most importantly … congratulations on your new mattress 
I’m looking forward to your feedback when you receive it.
