If you use a compactor bag for clothes/sleeping bag, etc, just make sure you have a plan if something gets wet. eg: your bag gets a bit wet with condensation (whoops). Are you putting that in with your clothes? Or where is it going if it's rainy the next couple days and you're hiking on?

I like a couple basic UL stuff sacks to keep my crap simple and isolate things if needed. I have never been able to justify the weight of compression bags, unless someone has their space 100% maxed out and can't do anything else about it.
