I have had to switch to the medium prong because I found with the small prong it kept flipping inside out on me the few times I had to give a stiffer correction to my dog for "flipping me the bird" which she does on a semi regular basis.
My medium prong is the quick release one. I only use the quick release function for taking the prong off because it is a major pain to put on that way.
