Do you need a sub if mains hit 35 Hz?

My mains are -3dB at 35 Hz in-room. Part of me says that is enough for music. The other part wants the sub for the bottom octave and the modal smoothing of going multi-sub.

Where do you land?

For 2-channel music, 35Hz mains are plenty. The sub argument is really about multiple sources smoothing the room, not extension.

Once you hear a well-integrated sub on music you cannot un-hear it. Slippery slope.
