CF,
True, however depending on where one is, freq congestion may prevent it.
Where I am it will be helicopter for all xmissions in the blind, such as at an uncontrolled field.
With a tower or departure/approach I'll use helicopter thrice, when first contacting the facility, when contacting them to request a freq chnge, and for the acknowledgement to their response thereof.
Between those times it's usually just the last three, such as 4VH.
