The socks are now also finished and I really like the result. All details, you can see on my Ravelry page. Otherwise, I have to say that I like knitting toe-up and this way of knitting the heel is the most simple, I know. Also I followed the recommendation of Regina and have split the ball into two and controlled the weight with a scale. Worked out great. There is only about 1m/1yd thread left. I think I'm going to knit right away another pair of socks that way because I really enjoyed it.
