Just wondering why you're going to be using the CPR and the Remora? Is the CPR going to be an aquafuge or a BakPak? You might considering building the aquafuge yourself if that's what you're refering to when you said CPR. They are really simple and I think just about anybody could do it. If you were planning on using a BakPak and a Remora I would say that's probably overkill and you could save yourself some money.
