Nick, that is odd, I like to use Z on caboose and haven't seen any issues with them.
I’ve used Z as well, with mixed results. I tried them on some of my locos, but the size was just a little off and I ended up with issues around plows. I didn’t have any problems when I put them on rolling stock, I just like the look of the TS couplers better.
You know if you run your trains fast enough you can't even see them thar couplers. Heck, you can even use Rapidos and no one would be the wiser!
