Are all the balls on the website for sale regulation balls. I also see that with the foosball men no alterations can be made why are there men with rectangle feet by manufacturer and then some tables like tornado and others have different pattern and structure to their feet with a narrow base to them instead of a wide base but longer? Which im trying to find for a 5/8 rod and 25mm screw hole to a nut in the back if anyone knows where to buy them for md sports 56" the only affordable table for regulation besides .5 off the width and 2 off the height for couple hundred.
