I can tell you Kevin that the AG 8X2 + also switches very well using the BCD connections to the Flex 6K usb ports. That method does not allow for switching to 60M at this time. Also , if you do not require SO2R inter connectivity, the 6X1 or 8X1 Genius is a less expensive choice. Personally I prefer the flexibility of the 8X2+. when used with a Flex radio with 2 ADC's and the PG XL amplifier.
