Hi Mark,
I'm planning a similar exercise but with 3750 switches, and one thing to keep in mind is the total number of EtherChannels supported by the platform e.g. StackWise supports up to 12 across the whole stack, so that's the max. number of teams, too. Dunno what the 3560 limit is, but it's something to bear in mind, perhaps!
Regards,
Andy.
