I have a 33" waist, putting me right between medium and large. Can anyone speak to the fit?

True to size! Go with the large.

What size would be appropriate for someone with a 30" waist?

There sizing was correct. I am a 32/33 and I purchased the medium. Fits great.

How exactly does the 4th strap go and fit?

Prefer your size everything will be fit perfect....
