I have a Sirui VA-5 head with TY-70A Plate for my spotter. Not sure if i'm doing something wrong or if the head is defective but even with locking the plate down with the thumb knob it is still able to slide and gets stopped by the retaining pin.
Anyone with this combo; does your plate slide when the lock is engaged?
