What does your SOP say?
What does your SOP say? If your SOP doesn't specify, then this issue falls into the 'technique' bucket....not the SOP bucket.
Airbus pilots do not have their hands on the thrust levers after V1.
(At least this was my company's SOP....I believe it is Airbus SOP, as well.)
Of course, for the Boeing, you can wear your outdated headset over your hat. Then, during rotation, you can grunt, make faces, etc., as you use both hands to rotate. At some point, you can get on the radio and say,
"Calling Rangoon...Calling Rangoon....Come in Rangoon."
