I really, really like the circuit. Being a student and a MYOG dude, when I build a sub 16oz pack that I'm happy with, I will replace the circuit, but not until next year.
NCNP is not like other parks, with blanket regulations regarding bear canisters. They are required some places, but not in most. I didn't carry a canister all year this year, which was nice.
The other thing is when the wife comes (which was on over 150 miles of backpacking this summer), I carry a two person shelter (lunar duo) and a stove setup for freezer bag cooking (jetboil sol). Also, I use the circuit for mountaineering, where I can carry 10 lbs or more of additional gear.
Spare rope other than the bear line? I don't have deodorant...?
