I've finally decided to switch from my trusty Potable Aqua tablets to a water filter as the primary water purifier for my backpacking trips. But now which one? Its primary use will be for three season, 3-5 night trips, and it will occupy the kit in my jeep the rest of the time. I have tentatively narrowed my choices to the MSR Mini Works and the Sweetwater Guardian and was wondering if anyone has any opinions on either of these. Also, if I'm overlooking a filter that I should consider, Please let me know.

Thanks in advance.
Chris.
