Yeah Ghee is good for a lot of things.
I experimented with coconut oil for a while, it gives some weird results because of the flavour.
I never noticed the low smoke with sesame, I've always found it very heat resistant. I of course never use it alone so that may be where it isn't too good but that would just be the overpowering taste. I might test it with the thermopen one day.
I sometimes mix it with the peanut oil at the start (say if I'm frying something quick to put in something else) or I put it in the finishing sauce, oil, chilli, soy etc. if it's fried noodles or something.
