Deodorant

This one goes out to all the guys out there… What antiperspirant or deodorant do you use? I was using a few of the different Old Spice products for a few years, but recently (either due to change in formula or me getting old) I started reacting to them so I have to switch… I first picked Mitchum, because it didn’t have any perfume, and it worked fairly well, but it does this nasty caking thing which just grosses me out…

So I am looking for endorsements, and looking for a deodorant that doesn’t smell too strongly but does the job, and doesn’t cause you to break out into hives… =)
