Thanks Nino, and thanks for your help with the topper domes and plastics 

I took the game off the trolley this afternoon while Ian (howzat) was over and we played a few games on it (Ian is my official game tester and play tests every game before it leaves)  It has his seal of approval 

It plays FAST!! It was actually TOO fast (and tilted easily) as i had the leg levellers set too steep at the back. After resetting the levellers front and back and adjusting the tilt slightly, it played much better
