I know how this feels Braddo, 

I had a good mate over to play some games, and he was pushing the pin all over the place, was feeling nervous watching it, I did not have the tilt set up then, but I do now.....
He saw nothing wrong in how he was playing, and I guess when I was a kid down at the arcade you would tilt them as far as you could get away with.
He has been back for a game since I set the tilt up, had a few whinges when he locked it up, but I am a lot more relaxed when we play now.

Cheers
Dave
