I think I like the heel... it's certainly a lot easier to knit than the heel flap. Not as easy as the afterthought heel, but on the upside - no extra ends to weave in! The FLK-heel is my first attempt at a short row heel.
Now that I'm no longer knitting socks, I've returned to Martina Behm's Sleeves for my sister. I'm about 2/3s of the way through the first sleeve.
