Well, the problem about the newer sites is, that you can play
Sirannon Ruins at Site 7 to add 10 base twilight, plus the twilight the comps give, so even solo decks (besides cards like
safe passage) add 11 twilgiht at Site 7, and with site manipulation,
Sirannon ruins can be replayed another two times, so I generally don't see choke being a very good strategy in Standard or Expanded.
