In answer to queries:  1.  To generate a blunt ended plasmid, I cut it with SmaI.  2.  I did also dephosphatase the plasmid.  This worked as I tested this by comparing normal digested plasmid to dephosphatased plasmid when transforming the bacteria.

HI !

Do you plan to keep the SmaI site ?
If not, how about adding 3'-overhang A's & T's to your inserts and
vectors and perform TA-ligation ?
Just a thought.....

Hope this is useful info.   :-)
