I was clearly refering to Roger's plataform stance. Now you are talking about pinpointer stance which uses a total different approach in terms of weight distribution. (apples to oranges kind of comparison) Because the weight distribution is different, the arche's bow is also different (more pronounced in the pinpointer stance) in order to keep the balance.
