Cisco recommended version for C6832-X-LE?

[Adam.angell]

I see cisco does not have gold star for any IOS version of C6832-X-LE.

Is there an cisco recommended IOS version for C6832-X-LE?

Last stable we have tested was :  15.4.1-SY4  - then mograte to Cat 9K

But before upgrade make sure you read the release notes and understand the caveats. also check any micro code upgrade required, if you moving from lower version

Regardless if the IOS has a "star" next to it or not, I can say, with extreme confidence, to STAY THE F*CK AWAY FROM THE ENTIRE 15.5(1)SY train.  

Currently have several 6807/6880 and 6840 on 15.5(1)SY5 and I have several TAC cases.  I suspect TAC and the devs are "not motivated" to find the source of the issues we are seeing because of the Catalyst 9k.

NOTE: 

1. I have used 15.5(1)SY3, 15.5(1)SY4 and 15.5(1)SY5.  Previous version fixes one bug but opens new ones (plural).  
2. I am currently testing 15.5(1)SY6, however, it is too early to tell what the results are.
