Not OP, but I have one NanoHD upstairs, one IW-HD and one U6-IW. Basically bought them in that order when needed. The IW have the advantage to also act as Ethernet switch to a few devices like Apple TV and so on.

Wait what? Soccer, baseball and volleyball too? When will this madness stop?

It’s legal for basketball. There’s a documentary about it called Airbud. Not sure about football, though.
