Are you referring to the stock rubber pad or the neoprene pad that normally ships with a Sorbo Buddy pack?
If you're retaining the stock rubber pad, then you only need to use a 1/8" sorbo. In your nomenclature, it would be piston head, sorbo, stock pad
If you're ditching the stock rubber pad and using the neoprene pad, then it would be piston head, neoprene pad, sorbo pad.
