I have used high fidelity blends from invitrogen (Platinum high 
fidelity taq) and eppendorf (triple master), and both seem to 
give superior yield and fidelity to Taq alone. The fidelity is 
not as high as you would get using just a proof-reading enzyme, 
but the presence of the Taq in the blend does mean that the 
product can be used in TA cloning.
