You're both right!  When I ran the analysis prior to writing the abstract,
Monolophosaurus came out as the sister group to Avetheropoda.  However,
adding and modifying the characters due to new taxa and observations,
Monolophosaurus came out as the sister group to Allosauroidea within
Carnosauria.  Either position seems reasonable to me, but I currently prefer
the latter.
