Synthetic and Natural are not Substitutablele WR... We know that they are not... Synthetic is synthetic..But natural can be transfered into Synthetic in order to compete in a more lucative market. Vein Graphite and in it's purest form can be transfered more economically into synthetic... and that is the market that Zenyatta is going after. The synthetic graphite that is produce this way has more desirable properties because it was produced from graphite in it's Natural form... Now, if you disagree with this anology.... tell me why and I can maybe see more clearly the point you are trying to make...
