Hi all
So none of my edge switches become root, is it good practice to change the priority on them to 61440 ?
cheers

It's far more important to make sure the STP root and STP secondary are lower than 32768 which you can do manually or with the macro "spanning-tree vlan
You can make edge switches greater than 32768 but if you are going to go to that trouble it is much easier to simply configure the above.

Hello,
To configure a VLAN instance to become the root bridge, enter the spanning-tree vlan vlan_ID root command to modify the bridge priority from the default value (32768) to a significantly lower value.
Router# configure terminal
Router(config)# spanning-tree vlan vlan_ID root primary
Router(config)# end
If you configure as a root primary, then none of your edge switch become root.
