In the past I have used the system of :
(1) AquaMira (3oz)
(2) 2 one-liter platypus bottles (2oz)
(3) 1 two-liter platypus carrier for camp (2oz)
(4) 22 oz AquaMira filter bottle attached to hipbelt (6.4oz)
When I come to water sources I use the filter bottle to drink as much as possible, while I wait for the AquaMira to do the job.
I also use the 22 oz bottle for drink mixes, etc.
I recently received the Camelback (70oz) Un-Bottle hydration bag as a gift and I believe I would drink more water with this system.
My reservations are the Camelback is 10.1 oz empty and I have considered maybe going with the platypus hydration bag.
I would like to hear what type of systems all of you use and advantages, etc---we all might get some new ideas !!
