From what i observed these months:
307 gets its cameos mainly from 970.
300 gets its cameos mainly from 176, 180 & 190
176 gets its cameos mainly from 300
975 gets its cameos mainly from 75 & BB feeders.
985 gets its cameos mainly from 975 & 851
From my side:
2 of 859 mercz perms stuck on 178 more than once in the weekends
though, 745S and 762S, even though it can get any random perm to
start.
187 wise still gets any random perm to start
858's status ditto, along with the rest.
By the way, feeder services always has the bigger say over the
trunk though, especially in woodlands, where rigids from other
services are taken.
