I had similar problems with the Promega Taq with <Promega's 10X 
buffer.  The Cetus Taq had similar problems in the same buffer.
Switching to the Cetus buffer cured the problem.  With this buffer,
or modifications of it which <i make up myself now, I get identical
results with either Taq.  Try Promega Taq in storage buffer B and make
up your own reaction buffers - saves bundles of money!
