Coffee Appreciation

So because the absolute top Baristas in the world can froth milk (very) successfully without a thermo, that means that total amateurs shouldn't use it as a training tool?
I don't make hundreds of cappas a week, therefore I need all the help I can get to nail the drinks I make.

Maybe you should read my post again.

"I've got one off ebay for a tenner but don't use it much now (every now and then to check my method). Generally when it starts to warm - that's your stretching done and when it's getting to be too hot to touch, you're all done."

I have a thermo. I used it to measure temps and now just use my hands because I can. I don't see why other people couldn't do the same and those videos basically show this reasoning to be the case.
