Just got a Muhle R89 and shaved with it this morning.
It's everything I've read about and more! :mrgreen:
Ok, so it's not quite as heavy or sturdy as the HD, and the handle feels a little bit tinny (in comparison!) but wow, what a shave.
It's definitely a notch or two milder than the HD, which was almost right for me, but i did have occasional bad days with it. ATG pass was effortless using a Crystal.
Very impressed - shave was very comfortable, not a spot of blood, and only very mild irritation on the right hand side of my neck (which vanished after 10 mins or so).
The only negative, for me, was the fact that it's a three-piece. It's a bit more effort to load than the HD, but I believe this is worth it. The blade sits dead straight, with no margin for error.
The HD allows improper loading as there is some play. It's possible to load the blade at a slight angle, if you're not careful!
