I just went through the same problem.   My solution was to transform,
make a master replica on nitrocelulose, grow this, then make replicas
from the cells grown on the nitrocellose.   Then the colonies stayed on
the filters in a more homogeneous way.    Lifting colonies off agar did
result in very uneven transfer, but I tried to reduce background false
positives by hybridizing for only 4 hours.
