I would have thought the center pin would be smaller for higher Z connections 
(???).

Look at the size of the center conductor in a piece of RG-59/U.

Although, as usual I may have that completely wrong.

I had a similar frustrating problem with a BNC patch lead. I bought some cheap 
leads at a rally and I didn’t notice that the plugs were 75 Ohms. The leads 
worked OK, but the centre pin was thicker than the 50 Ohm version and it 
splayed out the centre connector of the socket, so when I plugged a 50 Ohm 
patch cable back in, the centre pin did not make contact any more. It took me a 
long time to find the cause, and now all the 75 Ohm leads are in the bin.
