Do you recommend 40D nails or 60D for 15x22 putting green installation

You can use either nail for your artificial grass installations, they both will work out well to give you satisfactory results: the 40 D nails is a bit thinner and shorter and cost less, some installers like it as it can be a bit easier to drive through the turf at the installation; 60 D nails are bit more expensive but longer which theoretically provide better hold.
