Chris,
Today is the one-year anniversary of my first BHR (second was done 4/4/08) and I am a very happy hippy! I'm sure you do and will have many questions. Rest assured that most of the people on this site are more than happy to share their experiences.
I am hoping that I don't need to even think about revisions until at least 15-20 years from now and I have every reason to believe it will be longer, if ever, before I have to worry about it. The BHR procedure made sense to me because, as I'm sure you already know, it preserves more bone and is easier to revise if that becomes necessary.
Obviously, everyone recovers at a different rate, but in general, barring unusual circumstances, I think it's probably safe to assume that you will be able to return to work at 4-5 weeks. I was teleworking and getting a fair amount of work done from home after about a week.
Gotta run now, but I'd be happy to share my experiences with you.
Jim
