No the one adding friction to his cars is limiting himself, either on the number of cars he can pull or which cars can be on the end of the train. I'm not obsessed with it, but I would like to find a solution. I am glad Micro-Trains found a solution to the big ugly Rapido. I'm also glad someone found the solution to running multiple trains on the same track without having to throw a bunch of toggles. I'm also glad people have found better drive trains for our locos than what we had 40 years ago. If everyone was satisfied with the status quo and never tried to find solutions to problems they see, the hobby would never have progressed to the wonderful state it is in now. I have seriously considered switching out my Micro-Trains couplers for Accumates, but currently you can't even buy them separately right now, you can only purchase them with the trucks, and I'm not going to go to that expense (an extra couple of dollars per car I was ok with, but not $4-$5 a car). Actually, Accumates are almost the exact same size as Micro-Trains and McHenry's are just a hair longer. If you buy trucks with them they stick out a lot further because they are mounted further out on the truck. An Accumate mounted in a Micro-Trains coupler pocket gives the same coupling distance, has no slinky action, and in my experience works almost if not just as well as Micro-Trains(and in my opinion actually looks a little better). This is the route I would have gone when I was considering converting to Accumates.
