Hi Don,

we use regularly Taq and Pwo in our lab. We rarely had problems with 
both of them using standard PCR procedures, however the yield with Pwo is 
lower. It helps if you increasingly lengthen the extension step for the last 
10-20 cycles.
For really tough templates, we use Expand HiFi and it has never failed us 
so far, however the fidelity is lower.

This is all I can tell you with the information you provided.

Good Luck
