Well as I said many times LAGs are tricky :)
Therefore QOS on LAGs is tricky as well,
e.g. if you police the VLAN to 120M on a 4x10G LAG each link gets only 40M if
more than 40M worth of streams gets hashed on one link you get into trouble.
And it takes quite a fiddling to get Juniper LAGs failover/recover under 50ms.
