New here. Just ordered this as well!
Never had braces or an appliance before, but I prefer the idea of metal to plastic, so this immediately caught my eye.
After enquiring over email, I opted to get HG tubes on the upper 6's, and the Herbst is being moved back to the upper 7's to accommodate them.
I suspect that it might be a little too uncomfortable to add the face bow anytime soon - but at least I have the option. I definitely plan to eat well beforehand!
I also asked if they can leave the occlusal surfaces completely covered with the cast silver (unlike with the holes/gaps shown in the photos). Shop support said they are covered as standard, so fingers crossed for that.
I'm a mixed bag of emotions. Nervous about fitting, and pain, but also very excited!
