I haven't in years, but in the 1980s, I used to carry OC spray that was twice as strong as the ones carried by the PD back then, and I provided it to some of the Local PD officers who wanted something better than the Dept had purchased.
Got a Stun Gun/Taser? 6-cell flashlight which is NOT a club, but a flashlight? Got a legal length accessible knife? Metal barrelled inkpen? small flashlight, not a kubaton? got an umbrella with pointy thing on the end? Bat Masterson cane? got a 3 foot long HEAVY chain keychain? don't laugh, people notice my keychain, I rarely lock my keys inside, I notice the lack of weight ... (Richardson Police own the nunchucks I used to own in the 1970s, because a friend had them in his car when he shouldn't have... they were an illegal "club")
I have no experience with the GEL/FOAM type streaming "sprays" which which may not be blown back in your own face by wind ... sorry I'm not much help.
(Personally, I put a dead fish in my pocket and minced onions and garlic under my armpits ... no one comes near enough to me to bother me anyway, but then I don't have to go places defenseless very often)
