hermit shack is cool, i prefer wilderness because there is a pond not far from it that you can get water from. plus i like the hills all around it better too. hermits shack isn't as glamorous. i have never camped at butterfly springs, but i think it is nestled up on a hill or something. you go right by the trail to it on the way to hermit shack.
hints about bping:
the first timw you go you begin to understand what you really want and need out there. you will most likely carry too much stuff you don't need and not enough of the stuff you really need.
encouraging, huh? i know i did. but the more you do it, the more you will refine it. it is all about scrutinizing your gear to the max. "do i really need this?" and you start looking for multipurpose stuff real fast because that weight is a fun killer!
i really suggest you look into water purifiers, at least as a safety precaution if nothing else. water is essential! but it is also VERY heavy! They also sell very small and light bping stoves you could use to boil the water. hcsna is very upscale because they have fire rings at all the primitive sites and allow you to gather fire wood. so the stove is no necessity out there.
