You make a good point; the buds must be of the highest quality so that the end is wrapped tightly and doesn't feel like cotton wool. In reality, it's Johnson & Johnson or nothing.
Paperclips are good, but I once poked a little too far and thought for a moment that I had punctured my eardrum. This caused me to ease off pushing metal implements into my head.
There's nothing like using a paperclip and hitting a reach seam of dark brown gunge, though. Tremendously satisfying - and it feels like much better sport when you use a paperclip rather than a cotton bud.
