So far, I have had very good success with SP7 and want to look at moving all of the servers that I support to this level. The only ones that I'm hesitant about are some rock solid NW65 SP5 servers that are in a shared scsi cluster configuration. I vaguely remember cluster issues early with SP6 and just never went there with these servers. They are rock solid and running well, but if SP7 is as stable, I'd like to move to it.

Any cluster specific concerns or issues? Just file/print/iprint/GroupWise as cluster resources. Pretty straightforward.
