I just got all 8 sample waxes, haven't tried them yet. I smelled them, and really loved Orange Crush (soft wax). Banana armor is another very nice one. Hard Candy is similar to Fuzion (berry), and Rainforest is kinda melon/pinnacle scent. Very nice.
Back to the topic, with hard wax you suppose to get better durability, and thinner coat (more applications out of a jar), while with soft - little better look.
Why not just get all the samples, and throw SuperNatural sample in there too (I ordered that too!).
