Paragon - Yea, that is a bit overkill for my taste. Everyone has their own way of doing things though. I keep redunancy in other areas like fire. Two layers, like bivvy & poncho, in addition to my clothing is adequate for me. If I'll be in conditions which require more, I plan accordingly. I do think you should keep the filter straw though. I keep one in my larger kit as well. Yea, they aren't as good as a real filter, but it is better to have it in case you run out of purification tablets or your water containers fail you. My filter straw is my last resort, before drinking untreated. Again, it is good to know the limitations of your equipment.

OhioHiker - I'll take the dry road. I last a lot longer that way. It's also much better if things go south and you have to spend the night. If you're already wet and it dips into the 30's at night, you've set yourself up for hypothermia.
