Ok, I got my Innorel setup linked above. Feels like a solid bit of kit. Only have an air rifle on there right now... still waiting on PAL...
Ball locks up nicely and pivots smoothly. The Pan, I would like to see hold a little better. Also the knob for pan seems to back out some on it's own and becomes too easy to pivot. I may try to add some orings between knob and base to see if the friction will keep it in place.
Overall I am happy with my purchase, especially since being in a wheelchair it gives me more options than shooting from a bench.
