6807 VSS code stability (15.5.1.SY4)

The Cisco software page for Sup 2T VSS 6807  code 15.5.1.SY4 has a review stating that the code is unstable with tracebacks with blade 32P10G.   The notes state the SY4 uses a new FPGA process for that blade.  This worries me.  Has anyone tried this code with success?  

 

In addition, are they any "gotchas" when downgrading.  Could I downgrade from 15.5 back to 15.2 using the FSU process?  thank you

Currently using 15.5(1)SY3 without any issues.
I don't use ISSU or FSU/eFSU to perform upgrade/downgrade.

Thank you for the confirmation of SY3.
