If you put "opinion" at the end of that, you get hammered less.
Opinion.
Some folks like big couplers - when I was a kid, I was enamored of them, having only those funny things with the barb sticking out. Then in the early 1950s I lusted after that short Lionel vista dome with the flat groove below the windows. I could watch those department store layouts for hours. It all looked great.
Now I cannot even handle the fact that our track gauge is slightly too wide. At least I know how to do something about it. The hobby has something for everyone - if I could afford it and had the time, all of my models would have Protocraft couplers. In the meantime, Kadees go where I uncouple a lot, and dummies go everywhere else.
