Controller upgrade question

Looking for suggestions on an upgrade in controllers.
I have an older Tyco Pro track system that I have revived and am racing with but I was having some issues with the newer (primarily 440X2) cars I was running. My controller was getting hot and the cars struggled at times to get going. Forum member TuscoTodd suggested I upgrade my controllers from the originals, with the thought of grabbing Parma controllers.
Todd’s thought was to look for something in the 45 – 60 ohm range, but thought I should throw that question out to the group just to make sure that was the appropriate range of controller to seek out.
Does that sound about right?
Thanks.
Mike
