Re: For whom the mat calls..
I think that will depend on the demographic of your dojo. In a "college" town the diversity will be far greater than a more "traditional town. The dojo I train at is a Tomiki school and attracts more males than females. We have had some women come and go over the years. Our style includes chokes and mat work and can be intimidating to some who are not used to that and/or not comfortable. Usually it is with older people not under the age of 25.
