Preflop raise sizes seem relevant. With a 3BB preflop raise we´d make a cbet around 4-5BB, facing a 12-15BB raise making it

7BB + 5BB + 15BB => 27:10 and roughly 8:1 stack odds on the flop call, which for sure isn´t enough with 9 outs only considering the next street.

Generally b/3b seems the better option, as it´s kinda dumb to wait for our equity dropping down to put more money in, plus depending on the villians ranges there for sure is decent FE for b/3b with ~80 behind on flop.
