Hello all.
I currently have a Katadyn hiker Pro, and I am thinking that for a group that isn't the best choice for cleaning water fast. Would a gravity type water filter work better for a group larger than 2? I have been looking at
Playtypus

and then
Sawyer

I am not familiar with this type but would they be better?
