Has anybody got one of these? I need a replacement for my rod system which is just too slow and fiddly when attempting to change lenses in the field.

"Ronsrail" would have been first choice but I think gone out of business.

I've had a look at "Really Right Stuff" web site and even e-corresponded with them but very difficult to pin down exactly what I need from them for my XLH1.
