In reply to metal arms:
Thanks.
There was a time when having a rescue top-rope system to hand was a controversial practice (Staffs grit, late 70's, anyone). Not that I imagine a cameraman on an ab rope could do a lot for you on this route.
It's an interesting question whether people do these things with the camera there or stage the photo later. If it was me I'd definitely do the latter, but I guess the pros are probably cooler about being filmed than we punters.
