Reverting back to hook & horn couplers?

[RobertInOntario]

I have a small 3.5x5.5 layout, which I usually use for operating my British trains but occasionally I like to run my North American HO stock on it. It seems that my (generally smaller) British trains can cope with its 15"R curves better than my North American ones. The knuckle couplers on many of my coaches don't like these tight curves & often uncouple. Just wondering if I should switch back to the more reliable hook & horn couplers, even though they're less realistic? I'm tired of experimenting with different kinds of Kadees to find ones that work.

Thanks,
Rob
