A-tailing of PCR products

I am using a degenerate PCR strategy to amplify fragments of expressed
members of a subfamily of genes; I am ligating the products into a
T-vector.  I use a 15' 72C incubation at the end of the PCR cycles to
add the A-tails.  Is this sufficient to add A-tails to my products or
should I purify the products and A-tail them in a subsequent reaction
in which dATP is the only nucleotide available?  Thanks, C-
