I know I'm really late to the party here...
But I also highly recommend Blinc - it is amazing! My eyes get irritated so easily and this doesn't cause any problems at all.
AND, for those of you who like Blinc, but would like some more definition, try the blinc lash primer - WOW - I have long lashes so don't need it, but when I do use it, its amazing the difference - much longer thicker lashes - and you can add a few layers of the primer to get to the desired look. (It's white, and takes a minute or so to dry).
I'm really keen to read how your experimenting goes Becky! I'd never worn mascara regularly until I was gifted my blinc set and now I wear it every single day and love what it does
