Hehe, I have both of those badges. Always been a big fan of the heart too!! And personally, for me it would be a little weird to get a tattoo of my own name... but yeah, I agree with Steph, you've got to choose what you're happy to get permanently... stick each one on your mirror for 6-12 months and see which one you prefer to wake up to every day for so long, or maybe you'll get over both of them, you never know. My friend did the mirror thing though and she said it really helped her decide which ones were just a phase and which ones she really did like.
I really like the heart, maybe Good Charlotte just written in another place so it won't really look like some kind of cover on body ;) but think twice before you get it, best ideas come later ;)
