Should i get a rook or a snug piercing?

Ok so i have been looking into getting another ear piercing for a while, i have already got 2 lobe piercings on each side and a nose piercing. I'm interested in both the rook and the snug piercing but can't afford to get both! So which one do you think is likely to be the best for me.
i'm no overly bothered about pain levels.
which one is less likely to get infected or have problems?
can i use headphones (iphone ones) with the piercing?
and which one do you guys think would look best
if your'e anti piercings i do not wish for your opinion

Iphone Tumblr app won't save photos to camera roll?

A little after I downloaded ios 7, pictures from the Tumblr app would sometimes save and sometimes wouldn't save to my pictures.
