[c-nsp] Which Version for 6500?

[Jeffrey Ollie]

In a few hours I'll be upgrading the code on our Cat6500s that form
the core of our network. They've been up continuously for two years so
I want to go with something that's going work really well, but also
having the new call-home feature would be nice as well.  So the
question is should I go with 12.2(33)SXH or 12.2(18)SXF12?  The
systems are currently running 12.2(18)SXD2 and 12.2(18)SXF1, and we're
just using some basic L2 and L3 switching.
