Interface Recommendation for My CDU

[Warhog]

I've started building my CDU and have the panel and PCB ready for my CNC mill.

 

The next item on the list is what interface would be best for this device. I am currently running 2 U-HID boards and 2 Phidgets64 boards through Helios. I was thinking of using the X-Keys board for the CDU and the MFD's as everything that would be connected to the board are strictly momentary on switches. I would also run this outside of Helios and use the key bindings DCS already has for the CDU on their options page.

 

I wanted to see if someone with more experience has a better board they would recommend for the CDU and MFD's considering what my current configuration is.
