Suggest that you not use Chinese engines. There are a number of American and European engines. A lot of them are better than the ST or EVO No need to support a communist country.
The Evolution 46 line engines are all excellent. I would certainly put any version of the Evo 46 up against any version of OS 46, which has the gold standard image to some people. I'll be interested in hearing of the comparable quality and power in those engines you are telling us about. While I understand your sentiments about China, just how far do you have to go to attempt to not buy anything made there???
