Hello ddeitch,
Welcome to the forums.
Unfortunately, this is a question that only you can answer.
My thoughts are that unless you are playing for a panel of Hammond/ Leslie aficionados, the vast majority of the audience won't know the difference.
The aficionados will know the difference regardless of whether it's Nord or Vent, but will perhaps forgive you based upon your stellar playing technique
Cheers, Hanon
