How's Vent Pol. for blunting overhangs?

[skorycd at mail.ncaur.usda.gov]

Nobody has mentioned Vent polymerase for blunting overhangs, in the most
recent thread of end-polishing.  New England Biolabs recommends Vent for both
5' overhang fill-ins and 3' overhang removal.  They didn't explain in the
catalog why it was the only one recommended for both applications.  I tried
it once with a difficult cloning (i.e. large unstable insert and no
blue/white screening) without any luck, but I'm not ready to give up on it.

Anyone else have experience with Vent?
