I moved to ME code 55 due to the Atlas shortage (almost complete unavailability) when I was ready to start track laying. I’ve used Atlas before this. I’d stick with ME at this point even if Atlas became available again, or if I had to tear everything up, move, and start over.
Personally, I like the fact ME holds its shape. It takes longer to shape it, but once shaped, it stays that way unless I change it. I like being able to shape it, remove it to my desk, cut and file the ends, and then replace it in shape.
As far as easements, I determine those when I lay the roadbed, so as long as I follow the center line of the roadbed, the results are pretty much the same.
I use Atlas code 55 turnouts, and have never had an issue meshing them up to the ME flex track.
Also, I have a different experience over which is more bullet proof than was previously posted. I’ve lost a lot more pieces of Atlas code 55 in the laying process than I have ME. Maybe it is just me or the way I am doing something.
Some complain that wheelset bounce off the molded spikes of Atlas code 55. They are certainly larger than those on ME, and I did have some cars bounce along in my last layout. But, I think that is limited to the older wheel sets with the huge flanges. I coverted to metal wheels back then and never had a problem with those on Atlas track, nor the low-profile wheels Micro Trains included and eventually adopted as their standard.
Oh, and like Wyatt, right now all my turnouts are “dead” frogs (turnout linkages/motors are not yet installed) and I have not had a problem. My fleet is four and six axle diesels along with switchers (Kato NW-2, Atlas VO1000), and none hesitate over the frog. Again, as Wyatt said, other parts of the turnout have had to be addressed, but not the frogs.
I think it boils down to whether you work better with stiffer or limper flex track. I thought stiffer would be a
