what species do you use?

When it comes to blading we all know of the energy wheel which not only adds weight BUT also give the said blade a species. So which do you use? Example: "I use Gasher/Cancer"
You mean clear wheel don't you? I use all types of clear wheels.
I believe we already have a thread for a favorite clear wheel. Either way, it would not really be a worthy thread, since the clear wheel also plays as an important variable competition-wise.
