Hey, I didn't see the rest of this thread, but I have been very curious about this question myself.
I found this on the topic,
In Figure 19-3, an EtherChannel of four workstations communicates with a router. Because the router is a single-MAC address device, source-based forwarding on the switch EtherChannel ensures that the switch uses all available bandwidth to the router. The router is configured for destination-based forwarding because the large number of workstations ensures that the traffic is evenly distributed from the router EtherChannel.
Use the option that provides the greatest variety in your configuration. For example, if the traffic on a channel is going only to a single MAC address, using the destination MAC address always chooses the same link in the channel; using source addresses or IP addresses might result in better load balancing.

Sorry for the really basic question, but am I correct in assuming that to
choose the "most efficient form of load-balancing" for traffic across an
etherchannel it will always depend on two things.
1) Switch type - If using 3550s mac is the only option
2) If using a 3560 then source-dest IP/MAC can be considered. So in this
case it would depend on the traffic type. So if we're within a single vlan
src-dst mac would be the solution, but if traffic is L3 then we'd want to
use IP.
Is that all there is to it, or is there something else I'm missing?
