In the back of the NEB catalog is a table of how well different enzymes
cut depending on how many bases are left from the end of the fragment.
One of your enzymes may be cutting poorly.  I seem to recall having trouble
with Bam myself in the past.  As others have suggested, we now almost
always subclone PCR products into the Invitrogen TA cloning vector
and then clone them out of that.
