Interesting question. I think Tisher's comment is very valid. I remember when mark set up his club with jumps et al for "more serious racers", whilst this and big jumps appeals to me, I was concerned about my little boy destroying his car and getting frustrated. Whether this was a factor for other racers too I can't say.
I came back to indoor racing as a hobby that I can share with my son, so this is my number 1 priority.
Having said all that, the table top could be a smidge bigger
