Hello Phil,
Load balancing strategy depends on traffic profile. In case of single default gateway in particular VLAN - mac method should be relevant. The idea here is to keep a single flow path unchanged.
Regarding balancing RFS units - please keep in mind that tunneled VLANs is anyway balanced in the cluster by default - i.e. half of VLANs are bridged on every cluster node (in your case). This apparently means that user traffic also tunneled between nodes to reach the target bridge or DIS depending on there AP adoption tunnel landed (please see “sh mint dis detail”). This basically means that communication between nodes is also important and should be effectively organised. Like using mentioned stack of switches.
Stack is totally good as long as it appear as a single unit and support LACP
port-channel load-balance src-dst-?
src-dst-ip Source and Destination IP address based load balancing
src-dst-mac Source and Destination Mac address based load balancing
