Are you looking for any features that 9.1 has to offer? If you
aren't, it may make your decision easier. Unfortunately there are
several 9.1 features that are just awesome. So, where you go from
here is going to depend on your risk tolerance and (more importantly)
your availability of testing resources. Testing of production-ish
workloads during the beta period are very much appreciated by the
community, so feel free to give it a shot as long as you understand
the risk involved (which are substantial).
One big risk with 9.1 early adoption is that you run the risk of
having to dump/reload if you go production while in the before the
build hits release candidate status (and sometimes, even then). So,
if you are running a 24x7 duty cycle that's something to think about.
