Hi Graham
I have two grips now and find them very useful for HH shooting .
They make the TC to be a little SWA , but add quite some weight to the camera . The grip is mounted with one screw and it takes only a couple of seconds to do so .
The grips also make the STC like an SWA . I have machined a little distancer , which can raise any VF by 10mm , so you can not only do a fall with the back by up to 18mm but also a raise for 10mm ( if you want to have less foreground ) .
The new grip feels very good in my hands , is very "smooth" and gives a safe feeling . Also the release button is at the right place for my long fingers .
But I must also say , regarding the design and beauty of an ALPA , the new grip can't compete with the rosewood grips . These are just beautiful but not as handy .
I can't say anything about the new sync cable , because I use the HB version of the first design and never had any trouble with that cable .
The ALPA people recommend to contact them directly per E-Mail for any problem . So don't hesitate to contact them .
