caution: i met through hikers 2 years ago who said they went through a particularly cold spell and their gravity filters froze. if you do go that route, understand that there are precautions that have to be put into place...
Thanks for the input everyone. I should make my decision by tomorrow.

i vote for hiker pro. i've never had a failure, so long as the filter is not filthy and overused. that puts pressure on the ingress/egress ports.
**plus.... you can get one of paul's gravity filters and use the katadyn filters in conjunction with it. now you've just created options: gravity and pump.
Not sure what the issue is with the waiting part.. But with the sawyer it isn't very long at all, it has awesome flow speed.. jmo...
We would be one step closer to world peace, if everyone slept in a hammock..
it's not just gravity filters it's any filter it can happen to
best thing to do in the winter is keep your filter after first use on your person ...i use to keep mine next to my base layer so my body heat would keep it from freezing.. the reason my pump cracked was i left it in my pack and forgot all about it till the morning... by then it was gone
and the sawyer filters are even worse for winter time use they crack really easy
if your worried about your filter cracking in the winter boil water or use drops ... other then that you need to keep it warm some way after first use
It puts the Underquilt on it's hammock ... It does this whenever it gets cold
A Sawyer 4L gravity system just arrived from rei today....dividend purchase.
A friend has used this for the past year and really liked it.
I second Rip Waverly's suggestion....in fact that is exactly how I'm set up to go. I also have installed the quick disconnects into my water bladder's water tube and I am able to pump or gravity flow directly into my bladder that can stay inside of my backpack...I just choose the way that I am going to go at the time and let the water flow.
