Hovering down wind? It's the same thing really.
Like ShyT I do at least one Class 1 back up each working day. It is the safest way to operate. There is always power in hand, the profile is written that way, the reject in the event of a power failure simple and easily controlled. You're putting the whole back up out of proportion. And as FNW says "it keeps you out of the avoid curve." and he should know, he's been teaching this stuff for long enough, and in his current job deals with these profiles several times a day.
Don't try to re-write the laws of physics, they were written long before you and I came along, and they work just fine. I'd always prefer a class 1 back up from most sites to batting along with the collective under my armpit. The only one I had any real doubts about was the S76 vertical, which is quite an aggressive, full power manouvre.
