Time to try an afterthought heel?

I cast on for a new sock a few days ago, just a basic stockinette sock. But I'm wondering if it's time to try an afterthought heel? Part of me is a little apprehensive after my toe-up disaster, they were the most uncomfortable socks ever. But I do like the idea that other than adding a small piece of scrap yarn, I can knit mindlessly for a very long time.

I think I might give it a try, still have a few inches to go before I need to decide.
