retardo question: black or green chips for 100/200?

[Oblivious]

In small stakes, there's a principle (a slightly stupid one if you ask me), that two chip games (10/20) tend to be tighter and not as soft as their three or four chip alternatives (15/30 and 20/40). Based on this principle, one chip games should be even worse, so the question: is 100/200 live a one (black) chip game, or is it a four (green) chip game?
