I agree Gavin, its the current pinheads that will have to pass on the lure of the silverball to our kids and our extended families children.
My eldest son is almost three, I put a chair in front of my pins and he does a great job playing, both flippers usually go at the same time but he actually waits for the ball to come down before flipping.  I can see some potential there, just hope he is still interested in them when he is a teenager.  Out of me three boys at least one should be interested in pins (I hope!!)
