I think 207 and 208 will have the same tub size. If you're using the "large" setting on the 407, the "large" setting on a 207/208 will give you the same thing, only with a full tub.
Presuming the timer increments are the same on the 207 and 407, a full fill on a 207 should drain as quickly as a "large" fill on your 407.
I get the same suds lock problem with my deep tub A712 sometimes as it ramps up for spin and during the spray rinse, but load size has nothing to do with it. Just today I washed some funky items on the lowest fill setting and it still suds locked going into the spray rinse.
