FWIW The WSM family of cases is not suited for the Encore & would be pure disaster in the Contender. You can put one in a Encore but will not be able to run it to the pressures it was designed for because of a large area of backthrust on the frame. A number of the 25's will give you the same performance as the 25 WSSM can without the problems. It is a great case design, but not for TC products.
