HP+ should hold up pretty well. APEX was just running a special on PF01 pads for $119. Don't know if they're still selling them for that price.
Sounds like you may need some ducts or different pads like others have said.
As far as consumables, the StopTech's will be considerably cheaper than any other BBK.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
