[GreenKeys] Vintage RTTY operating question

Please forgive the newbie ignorance.....
What is the best way to listen for RTTY in a high noise environment?
I can receive in LSB mode with 3.2kHz nominal bandwidth
- the downside is wider bandwidth means lower s/n.
- the upside is that the no-signal noise is broadband so the AGC keeps the
M/S noise low and the TTY doesn't chatter.
OR
I can receive in CW mode with 300 Hz nominal bandwidth and BFO set to 2100Hz
- the downside is that the no-signal noise is all concentrated near the M/S
frequencies so I get TTY chatter.
- The upside is presumably better s/n when a signal is present

Is the "solution" to use narrow-band CW mode with AGC disabled and use the
manual RF gain to keep chatter noise low?

Thanks in advance & Happy New Year
