From a functionality standpoint, twinax works just fine.  We're tying
our FEXes back into our 5k cores using them, and they work well
enough.

Personally, I hate the twinax form factor.  The cables are thick as
hell compared with fiber, and we've had several of the connections
break in high-volume racks.  That said, I think the connections that
broke were from stupidly cheap third party manufacturers, so take that
for what its worth.

If you're deploying those switches in a location where the cables
aren't going to get mucked with and you're not stuffing your cable
management arms to the breaking point, they'll work just fine.
