Don't forget that you've just swapped out pads with pretty good bite for pads that aren't quite as good. Getting used to track pads has probably skewed your perception of what all pads should feel like. Do you remember the first time you used the HP+ fairly hard, and how that compared to the OEM pads that you'd been used to before that?

If it helps any, Carbotech pads are clearly gentler on rotors than HP+, at least the XP8 which is kind of an entry-level track pad like the HP+. Supposedly swapping among the various Carbotech pads can be done without swapping or doing anything special with the rotors, but if you don't do a whole lot of street driving between track days it seems hardly worth it to bother. Just do a bleed when you're checking for adequate pad thickness shortly before your next track day.
