SGMA members were heavily involved in the design and testing process of the Ross Standard Gauge switches. Several prototypes were farmed out to SGMA members who put them through numerous test runs with every SG locomotive members had. In the end, the Ross switches operated so flawlessly that the prohibition in SGMA's module construction standards against having any switches located in our outside 87 mainline was modified to allow Ross switches, and only Ross switches, to be incorporated into the 87 mainline.
One thing of note, Ross switches come with LGB switch motors which cannot be operated on track current. To overcome that limitation, I recommend use of the aftermarket PIKO switch controller which was designed to operate LGB switch motors. This controller will take AC or DC current and covert it to the precise current needed to operate up to four LGB switch motors.
