Recently into these. Is there a list of all the plastics somewhere LOL?
There is a fairly large list of plastics, but the real problem is that there is little resemblance between runs of discs that are labeled the same. So, your Soft Wizard probably does not have the same flex, feel, and look as some else's Soft Wizard.
When Wizard throwers handle a Wizard that they particularly like, they generally buy up as many as they can from the same run, because there likely will never be any more like them - ever.
