Knotty - I am glad you love silk so much.  I love this forum too and how everyone is so passionate about "their" things, it would mess with my head if you started being a powerpro freak.  I think I love powerpro cos I'm still such a novice knotter, and it makes me feel good that I can use it without breaks and tears.
As we haven't heard from Sueki yet - in Aus, cack-handed, or cacky handed means left handed...  probs the same in the UK.
