I am SO confused. I'm dumping my MSR Sweetwater filter (weight). Purchased Aqua Mira drops. Thought I could use them alone. Thought maybe not. Purchased a Steripen. Am freaked out by reviews of technological mishaps. If I'm on the JMT for 9 days between resupplies, does that mean I have to carry 200 Micropur tabs as backup in case the Steripen flakes out on me! Am considering an AGG filter or Aqua Pro filter. But they suggest using Aqua Mira drops prior to filtering. But I thought I could use the drops on their own. So why filter as well? Help! Please point me in the right lightweight easy direction! Thanks, Barbara
