What do you mean by the twist retract mechanism? What is so amazing about the ROtring? It looks so basic and unusual that it almost seems impractical, but I have never even heard of it until today so. But really, why should someone drop $40 on a pencil, this specific one? Maybe I can be convinced to order it and try it out at least, ill probably be too lazy to return it anyways so im preparing that if i go through with it, ill have spent $40 on something I may hardly use.

And the Staedtler, how is it weighted and how is it a drawback? Is it like too heavy, too light, too top heavy, bottom weighted, etc.? What exactly?
