Just an echo of the replies you have already seen here, but for the most part, I will at least give something a try once (except for the nasties Like Doc mentioned). If I find I don't hate it after one, I'll grab a few more, or a fiver to really see if I like it. I find it's hard to really see if it's worth picking up a box from just one stick. Even after sampling a few, it can still be hit or miss on a box, but in general, they won't get worse with age if they're kept properly.
I must say don't just go by what others say, or the rating CA gives something. Those can be good starting points, but only you can decide what suits your taste buds. I've found there have been sticks that people rant and rave about that I couldn't stand, and vice versa. You never know until you give something a go!
