I did both to node M, since that one is more dangerous. AACI only at node L is generally enough, but it has to trigger.. I did not encounter too much problem at node L. Concentrating both to node L is definitely not necessary. At least send one to node M. You should see how things work out for you and change accordingly. ;)
