^^^^ Yeah, you're kind of in the middle for L or XL, or get the soma double ones that are about in between there. Some people think the somas are a little too small top to bottom, but they're fine for something like chucks or sambas, not so great if you want to wear combat boots or running shoes or something. You can bend them, though, and they're fine, it just takes some work.

If you're not riding fixed, super high quality straps aren't as important, but there are options from $5 nylon rigs (which I personally like) to weird rare Japanese and Italian stuff that costs more than a purebread puppy. There are tons of strap threads, you can read a few and get a good idea of what's out there, though you'll mostly just learn that nobody can agree on anything around here.
