XRAY - Model racing cars

Hi, i have the 2015 x12 and also an associated r5.1 wgt.. i want to change to the XRAY x10 wgt but dont know to choose the 2015 or the 2016..?

the 2015 x12 and x10 have many crossover parts and i like that...

I want to keep the crossover parts choice, so do i choose a new unbuilt 2015 x10 or go for the new 2016 x10?

The X10'16 also shares a lot of parts with the X12, but a few parts were changed on the X12'16, like the pod bulkheads (which some people don't like on the X12'16, but have potential to allow better ride height adjustments on the X10'16, so a swap might be a good idea!).
