using refillable ink & vapor lock

I have an Epson R3000. Not used yet, so no ink has been loaded in it. I recently ordered Cone Ink and all the refillable cartridges. Their cartridges hold bit more ink. But I then found out that the reason Epson's cartridges hold some ink at the end of the cartridge life and not let you use it is because of "Vapor Lock". The people I purchased the CONE ink from say there ink won't clog as easy as Epson's, and if you're worried you can see when their's are getting low and can refill them. I need some good opinions. I live in Albuquerque, New Mexico where there is no water in the air, I mean dry really dry. I like to explain this to others "nothing is designed for this climate". Thanks
