Best Styluses (Styli?) for the iPad Air?

Hey there. Will be purchasing an iPad Air tomorrow and I'm looking for the perfect stylus. I will primarily be using the stylus for writing in notes on power points & PDFs. I'd prefer a stylus with a fine-tip, but I'm not sure how those work exactly.

I've looked at The Verge's iPad Stylus review, but I'd still like to see what the general audience has to say.

Thanks.
