I think that George's point is that you get better turning and stability with the hardware at the back. You may be able to make up for any deficits in those areas easier than you can redirect the power. Bicycle chain or hollow shafting are popular for power transmission.
Toothed belts are quiet, efficient, and rust free, but require more space than link chain.
