I use an MSR that comes with a set of heat reflectors, including a base plate. I've never had a problem with overheating whatever surface the stove is on. As for the enamel cup, most have a metal handle that will get pretty hot and hard to hold, as well as the rim getting too hot to drink from directly. I like using a small pot (titanium) and a separate cup..while I'm eating or drinking the first part of my meal I'm heating water for the next phase.
