I have an assortment of different types of tobasco sauces on my desk at work, which one i use depends on my mood, lately its been the habanero sauce i've been using the most. I also try all the different hot sauces used by other guys at work, all of them do the job, i'm not really picky.
I about killed myself the first time I tried Endorphin Rush. I used it like it was steak sauce on a steak I was cooking. It's hot, but it tastes horrible.
