In corn they are very close, but that probably doesn't apply to you. In low yielding wheat, like we have out west they are very close, too. When the yield goes up, especially irrigated, the STS does quite a bit more. Walker loss sets the limit. In Europe it's different, because of the adons in the walker area. Have you tried a NH CXIJ We had a guy from Germany working for us one season and he likes the CX much better than the lexion. That's what they bought after trying both.
