I believe(haven't actually calculated) that the shafting will end up weighing about the same as the chain required to drive a similar system.

Last year I got annoyed with tensioning chain.

If I do it properly I won't have to worry about it breaking(though the same goes for a properly designed chain system).

It is different. Its cool.

Why not(seriously I would like to be critiqued. Though I probably don't have to ask on CD)?

I just checked out the weight issue a little bit. #35 rollerchain is about .275 lbs/foot
If you use 6 feet that is about 1.25 lbs
the shafting in this system only weighs about .25 lbs
If you went with #25 like a lot of teams the the chain is lighter

I still havn't looked into sprockets vs miter gear weight
