Joy, Have you tried the Maglus stylus? It's the one I'm most tempted to try, as an upgrade for my cheapo Amazon-type stylus (for notetaking and perhaps a bit of sketching). Thanks for your details posts on stylus products and apps!!
For me the king of iPad stylus is the Wacom Intuos Creative Stylus (Intuos Creative Stylus | Wacom)
It's beautiful to use but very much an artist's tool and not cheap! That said I do use it for writing a lot of notes and it's great.
Better still in certain apps it supports Palm Exclusion which means you can rest your hand on the tablet whilst you write!
