I have been using the Provo Craft interchangeable hooks and I love them. I have done bout 10 rows and my wrist does not hurt. Also my tension is better because I am not choking the hook.
On another note, I will be part of an art project. A woman my sister knows from Ravelry is doing her masters thesis in art. She is asking knitters and crocheters to send her pics of them doing the craft and a swatch of their work. She is then going to take the pics and recreate them as line drawings. The swatch will go over the pic at the show. People will lift the swatch to see the drawing. Pretty cool. I am working on my swatch now. My sister already sent the lady our pics.
