I always carry a waist throw bag as well as at least two more in the boat. I don't think it matters too much what throw bag you carry as long as you are able to use it quickly. I use a 1/4 inch spectra line because I can have 70 ft in a small bag and it has a 2200 lb breaking strength so with a couple of small pulleys, prusiks and some webbing, I can set up a Z rig from what I have on me without having to go back to get my big kit if time is a concern and I could reach the issue with the 70 ft. My setup is probably overkill. Carrying any throw bag on a waist belt that you can access quickly is the most likely required scenario.
