Get left seat and never trade it.
Captain is a manager on the airplane. Have you heard about manager of company to quit to become secretary in another? Get it right, go to biger plane now as FO or better get command and keep it for lifetime. I get my command on turboprop and never moved back, now I am Capt on wide-body and my advise is do not risk with FO for short time because slow down may make it extremally long time. Good luck!
