Hi guys
can see you are trying to getting numbers up.
Have a look at the attached thread from Norfolk buggy club
http://www.oople.com/forums/forumdisplay.php?f=51
It seems the things to make it a proper goer- running on floor as well as carpet, small jumps on carpet area, running buggy tyres and ability to modify track between rounds.
perhaps if theres any mileage in it you could post to thread.
