I've had the best results with the Fichtel-Sachs/Torpedo brand of coasters, even when on an IGH. I had a TCW 3 that stopped well but of course the brake disengages if you hit a false neutral so that will never do. CCM's seemed to be good when new, Majestic (Montreal) were adequate at best and as mentioned in the English 3 Speeds, the Perry B100 weren't good stoppers in my experience.
Fave is a two speed Duomatic on a 57 Sports with a front backup that's rarely called into use.
