Yeah I don't like Service Packs, I think it's better to cherry pick only SMUs 
that are relevant to bugs that you might run into.
And there's always a danger of reintroduction of bugs e.g. a SMU fixes recent 
bug but reintroduces bug that was fixed by some older SMU.

I have spent a non-trivial amount of time going through SMUs and testing upgrades. Considering that Cisco do not do testing of SMUs in any-to-any configuration, I am a big proponent of SPs, where the SP is properly tested, and contains all rollup bug fixes.

I've run into issues where two SMUs didn't work together, and when I complained I received the answer that this was never tested. I've also run into issues where all SMUs couldn't be applied together, requiring two reboots to apply all SMUs.

So... again, big proponent of properly tested SRs instead of SMU-hell.
