According to tracking they are here but I won't be able to start lacing them up until later today.
I'm afraid I don't expect them to be too different from the HEDs, HPlusSon or Kinlin I'm already riding/rode so I don't think I'll be much help.
Coming off factory wheels is a different story (road bike was a frame up build so I had custom wheels from day 1). You should feel a difference from those boat anchors you're spinning up.
