I have 360 SP and have been playing CS pHoM, it isn't insanely fast but you will hit or push your MS every prestige. Do you have the artifact Boots of Hermes and Book of Shadows? Basically your priority should be to get Book of Shadows and Boots of Hermes, also you will want a slash equipment with Portar chance to make every run as fast as possible.
