Sleeping bags that compress to the size of a football are going to be high fill down (not synthetic). Also, unless you are looking to go +$200, they are going to be rated not too much less than about 30*. I have a marmot that is 800 fill down that compresses to the size of a football, but was not cheap (in other words, snugpack and wiggys are not the only ones making the stuff).
As far as packs, I also have THE pack, and do not find it to be too useful for long hauls. It is a tough pack, but tough = heavy and the suspension is not set up for too much comfort IMHO. I recently picked up an osprey aether 60, and besides the gay color (black and yellow---but can be had in green/black), I love it. it is a 60 liter pack (dont know the cubic inches), which is much bigger than THE pack, but is probably half or a third the weight of THE pack. If you are fixing to do any serious backpack/living out of the thing, you should really look hard at something w/ good waist belts to save your back/shoulders, hense I would strongly recommend against THE pack. I searched for quite a while, reading a lot and trying on a ton of packs before I settled on the aether. Not saying it is the end-all, but I am convinced that for me, it is the best bag for the money. As said before, the straight-jacket (also heard it called burrito-wrap) compression system is the best Ive seen for flexibility as far as going maxed out capacity to converting it to a very minimalist day pack, and not have all your crap sink to the bottom ala rocks in a sock. Also, the main bag fabric used is not as bullet proof as the 1000d courdura on THE pack, but it is not nearly as flimsy feeling (to me) as the stuff used by the ultralight bags. Just seems to be a real good balance of all the aspects (that I think) make a good pack. But as said before, not all bodies are the same so what works for me may suck for you
they can be found at that REI store everyone keeps talking about (and because I didnt see it mentioned, anything you buy at rei can be returned AFTER you use it. if you think the thing sucks for any reason, take it back for 100% cash back).
