you should be fine with the Sphere plus it will provide you the easiest option to run either brushed or brushless. perfromance wise it should be up there with the rest even if you run brushed. i believe even top dogs run the sphere with brushed motors with no dip in performance
..... i could be wrong but i believe paul lemieux ran it at the worlds with his brushed mod ... and we all know he manged to finished 3rd overall.
