The most under rated beyblade parts

I have been doing lots of testing lately with some of the older parts and found that many of the parts that are said to be outclassed or just not good are actually very very useful, such as the fusion wheel "sol". So I was wondering... what parts do you think are the most under rated? (they dont have to be old)
