[j-nsp] SRX recommended software

[Jeff Rooney]

I have a few SRX650's that are running 10.4R9.2 per the Juniper recommended
release page  http://kb.juniper.net/InfoCenter/index?page=content&id=KB21476
However,
I just have a few more which came with 11.2R4.3 on them. Just curious as to
what everyone is running on these, should I downgrade the new guys? or
upgrade old?

The workload on these boxes is nothing crazy, some IPSEC vpn, OSPF with
about 200 routes, firewalling, no cluster...etc.

Thanks for any input.

Jeff
