If another Field Turf update won't send you screaming into the night, I visited McGuirk yesterday and took a look at the field turf now that the composite has been installed.
Interesting! During one of my previous visits, I (ahem) liberated a scrap of the field turf. The plastic field turf blades were measured to be about 2 inches long.
The composite, as installed on McGuirk, fills the space between the blades almost completely. Only about 3/8 to 1/2 inch of the plastic blades protrude from the composite.
That explains the amazing durability of the field turf. The players are actually standing on the composite, not the field turf. Pretty neat engineering.
The feel of the field turf was solid, but slightly "springy". I can see why football players like the stuff. There is a strong smell of new tires.
