Imo, the vocal has maybe the most important role in a bands identity. I don't think Falconer is Falconer without Blad, although Kriss did a great job, and yes he does have a voice which sound s a lot like Blad, but it isn't the same.
Falconer imo. without Blad is like Kamelot without Khan, or Opeth without Mikael Åkerfeldt.
I do agree to what someone said earlier, I have also had problems telling the difference some times.
As for the logo, it is practically the same thing, just in a different style, but I like the new style better.
