I was wondering if anyone here has a link to a good comparison study of the expenses and maintenance costs of an natural vs. synthetic sports field. if injury numbers are included that would be a benifit as well. i have found a few through a google search but wasn't sure if there is one that really stands out as better than the rest. I feel as many on here do that natural is better and would like to be able to better back it up or be proven wrong in this thinking. thanks in advance.
