27.1?

I have both the 27.2 and 27.0 posts, although I had just assumed the numbers were true. Perhaps I should measure them.

BF uses a tall mast. I think this one is mid-length, so a classic post might work in it. My other mast is tall with the post slammed to the bottom, so a shaped post would not work.

Anyway, I'm probably OK at the moment.
