I went into great detail in episode 82 podcast about the process. What you get here that is not on the podcast is pictures!
The combed locks skein is 50 yards 2 ply 17 WPI. It weighed 3/4 oz.
The skein from the pulled top is 33 yards 2 ply 15 WPI and weighs 1/2 oz.
A quick math calculation shows both skeins are close to about 15 yards 2 ply per 1/4 oz. not exactly but close enough for me to say the skeins are very similar. Based on that the bottom line is it does not really matter, choose your method based on what you like to do best for processing.
Several comments about the photos. I have not been able to get the iPad app to let me arrange the photos, or label them so if you see this before I get on the real computer and do some editing, come back later for those as well as a link to the podcast. Meanwhile, enjoy the pretty pictures.
