Which ingots do you prefer for Emax?

I would say broaden your horizon. Emax offers so many ingot types that its too hard to say in general. But I can say that HT ingots are good for posterior stain technique, but if the wax up is too thick, it will be too gray. You can also use Value ingots in these situations. LT ingots are good for copings, but I find value ingots to work slightly better if you have good build up control. Hope this helps.
