The Takli spindle (and bowl) arrived today, and I gave it a spin. It seems to work better for me than the Akha, but I probably benefited from the practice the Akha gave me of spindle spinning in general. I am finding that if I spin the fiber too thin, the metal "point" wears it through as I spin, and it breaks there. So, I'm going to have to do a little careful watching of some experienced spinners to watch the angle at which they hold the drafted fiber relative to the spindle.
It is great fun, though--cotton drafts so nicely!
