[c-nsp] uBR7246VXR - etherchannel outbound load balancing ?

As you can see I have a channel group with (2) underlying member ints.  I
have inbound loadbalancing working (which I don't believe has anything to do
with this cmts, but rather they 9k sending they traffic to the cmts). but my
question is why isn't the cmts load balancing outbound traffic over both of
its links?  Would seem to have something to do with the etherchannel load
balancing hash mechanism. like src-mac, src-dest-ip, etc, etc. but I don't
see any of those load balance tweaks as options in the cmts.. Is it possibly
?  if so, how?
