Once I tried Priscilla Gibson-Roberts short-row heel, I never turned back. It's a great heel and I can't imagine ever using another one (though it is fun to experiment). One of the things I like best about it is that all the stitches stay on one needle, and there is no counting and re-distributing stitches like in a heel a flap and gusset.
One thing I'm not crazy about in the PGR heel, however, is those little holes that tend to come right at the corners near the top. So I have modified the heel a bit, for my own use. I do a teeny little heel flap, 4 rows. Then I complete the heel like you'd normally do it. Then I pick up 3 stitches on each side, right on the teeny heel flaps. I decrease those new 6 stitches on every other row, as you would with a flap/gusset heel. Does that make sense? I hardly ever get those little holes when I do it this way. I think that by picking up stitches perpendicular to the existing knitting gives them extra strength and stability, and doesn't really give holes a chance to form.
You can click on the photo above to make it bigger. I think the dark blue of the heel makes it easier to see that little jog of 4 rows. Sorry about the lint and pilling on the heel, I didn't notice that until after I'd taken the photo. These are old socks. I love how the self-striping sock yarn stands up to wear. I've been wearing these socks more than 3 years.
I'd highly recommend Priscilla Gibson-Roberts book, Simple Socks: Plain and Fancy to anyone who wants to learn how to do these heels. A great book for any knitter's library.
