I take it you used straight Taq and not a proof-reading pol for the PCR? 
Pfu and similar will not incorporate dUTP (or analogues) due to their 
read-ahead function.

For Taq I would PCR using a dUTP:dTTP mix and verify that works before 
using the more expensive aa-dUTP. Optimising the ratio is probably the 
key, especially the longer the PCR product.

I love deadlines. I especially like the whooshing noise they make as
they go flying by.
