Hi Paul,
I think that NetFlow version 7 is not problem for most of netflow analyzers. 99% of all supports version 5, 7 and 9. In the version 5 and 7 you can get a static list of fields - more information you cannot get, because it is a static format. You can check the fields on the: http://netflow.caligare.com/netflow_format.htm
But you have right, that some analyzers don't report all fields (but usually you need only IP addresses, ports ...). Which information do you need to see?
On 6500 in hybrid mode, you need to configure netflow on both parts (MSFC and supervisor)... see netflow pages for configuration.
I'm working for a Caligare company. So I can offer you our product Caligare Flow Inspector (http://www.caligare.com), or I can recommend you other free tools (for example nfsen or ntop), but I think that they doesn't met all your requirements.
Feel free to contact me with any question.
Kind regards,
Jan
