I like the large better, but if you just a carry a spare tube and 1 cartridge, and you’re concerned with weight or aero, the small will work.
Ah, thank you, that's helpful. I recently got a bike that runs 47c rubber, and when I ordered to some tubes, I was surprised by how big they are compared to the usual 23, 25, or even 30c tubes I'm familiar with, so it has made finding a seat bag to carry the flat kit a real challenge. I need to break out a tape measure and see just how big these 47s are, but they don't even fit in a seat bag that I use to carry a 25c tube + mini tool + levers + gas + inflator!
