Same with the 757-200 we had... The AA ones, for example, have the 6 entry/exit/service doors and overwing exits, but ours had the same set up as the 767...
I prefer our arrangement on the 767... I like Door 3...
Door 1 - Dual lane slide raft (straight) "Form two lines... Jump! Jump!"
Door 2 - Dual lane slide raft (angled platform) "Form two lines... Stay on your feet... Keep moving!"
Door 3 - Single lane slide (angled platform) "Stay on your feet... Keep Moving!"
Door 4 - Dual lane slide raft (straight) "Form two lines... Jump! Jump!"
