Reply to "WHAT TRACK YOU LIKE BEST ????"

I have had layouts with GG (including GG switches, which I had Zero problems with, even using the diverging leg as the mainline) and (currently) with Atlas.  I give Atlas the edge for realism--if that is a consideration--but GG for economy and flexibility.  Atlas switch machines don't bother me because I don't use them:  I have ground throws on all my switches--which is perfectly prototypical for my region and era.  I do have one Atlas switch of an older variety whose connectivity gives me fits; I plan to replace it with a later version.
