I prefer single soft for DS or WW wipe down, double soft best for collecting polish, sealant, or wax. I haven't used the triple soft. On the interior you should not use polishing towels, I would use Adams utility towels.
I saw the same video that Michael saw and I tried putting a microfiber below the pad on the machine, but honestly it didn't work very well. You probably are better off just hand buffing, the machine was hard to control.
I would change your order for washing, by doing the wheels first, then spraying the car, then foaming, then 2 bucket washing and final rinse. I understand why you let the foam soak, but how come you don't reform the car after rinsing it?
