I like heel flaps. They FEEL like they've been handmade, and that's the wonderful thing! The other thing, when you use the slipstitch heel pattern, they're harder wearing than 'normal' knit heels. I found that if you slip the first stitch on every row when doing the heel flap, that there's no 'ridge' when picking up stitches.
If I wanted short row heel socks, I'd buy them..
