Wow! I just finished reading this whole thread and there are some great tips in here! 
I saw several recommendations for blinc mascara - I haven't used that, but I have used L'oreal's version of beauty tubes mascara and I love it. LOVE it. I don't know how it compares to blinc, but it costs much less. Here's a link:

The "tubes" do come off when I get wet, but they do not smudge when it's humid. And when they do come off, they keep their tube shape. In other words, no raccoon eyes, just some little black bits that you can easily wipe off your face. Hope this helps someone!
