Brooks b17 edge question

[Beane]

I measured my sit bones three times and came up with three diff measurements, but 160 would be my guess. So B17 might not work. I will give it more time though.

Below is pic of what I'm missing.. I don't think it's an important bone. At least when they took it out they said it was non weight bearing and didn't even prescribe any physical therapy. I do walk with a tiny limp though (or so my mom says).

p.s. They didn't put anything in to replace it, but a titanium rod would have been sweet!
