I also did some spinning on my Corgi Hill BFL. I am trying for a two ply lace weight.
I want to spin it thin and definitely need to add more twist. I am spinning it with loose tension at a ratio of 13.5:1. This is high for me but not high enough. Last Saturday, I took a spinning class from Nancy McGraw with my guild. She taught us a technique for measuring twist.
I like the yarn but the twist is less than 30 degrees. It is under spun and there will be even less twist after plying. Tomorrow, I will sample some more and try to get the twist angle between 35 to 55.
