I don't like the foam. Too easy for the person you are spraying to wipe it off of their eyeglasses and fling it back at you.
But, I have found OC to be like most things in life--the more experience you have with it, the better you handle it. Working in prisons the past 18 years I've eaten a lot of OC, CS, & CN--to the point that it isn't that big of a deal anymore. If you carry this stuff, get a little on you from time to time so that you know what to expect. It's good stuff, but it's not devastating to people who have experience with it, whether it be you or the ex-con who is attacking you.
