No doubt about that. The CTS is the most versatile and unfortunately, the most unsupported machine that JD has placed on the market. There is far too much reliance on the STS to be "the one" for all harvesting.
last 2 years I have run a 9760 STS and CTS II together in wheat and barley. The 9760 has a noticable capacity advantage over the CTS. But I am able to get a better sample out of the CTS.
