My GG switches worked fine in my yard, but did not always close completely, until I made some adjustments to the position of the switch motor. I have used Atlas and Z-Stuff switch motors. I have also used Atlas and Ross switches. All worked. The best (this could be sacriledge) were Lionel Fastrack.
I am considering Ross for my Standard gauge layout even though I could get GG a fraction of the cost. To me, you can compromise in a yard that is easily accessed but not on the main line.
