Just want to follow up on this thread because I was bugged and it has been two days. I bought the Bearikade and the Platypus filter system with new hose and new 2L bag. He was a pleasure to do business with and I did save a few bucks buying two items and by speaking with him directly. I wasn't going to do a 4L water system for two people, but I will tell you, I am lazy when it comes to doing my chores. I tend to want to fish instead if I have the chance, and giving my girlfriend something to do that is easy will contribute to her confidence in the field.
Instead of starting an online battle of wills and opines, if you are not interested move on. Why have the conflict? I personally spoke to someone with FAR more experience than I have, that also helped with my self confidence knowing that I am on the right track for a 220 mile trek and he provided me his packlist as a cross reference. He was a great source of information, is not new to the game, and I hope I made a new friend. Is it worth the extra $20? I am sure it will be down the road!!! If I have more questions, I know he will lend a hand.
Be kind to fellow BPL members, especially when they are "doing business" in an honest fashion and willing to lend a hand.
