Can't do BB to save my life, have had 2 gimpy shoulders my entire life, had surgery in one so if I try any barbell movements I will always, without a doubt, compensate with one and therefore end up selling myself short and being unable to lift well.
Dumbbells all the way for me, so, to answer your question, who knows? Weightlifting is also a matter of muscle memory, to which you are going to have very little when making the transition from DB to BB, so it will be a toss up regardless.
