Built 11 sudo-pushup greens 8 years ago. We basically blended, 50/50, topsoil & sand and built the greens to allow for surface drainage over the entire area of the green. Seeded to Penn Cross and hammer them with paclobutrazol to keep the poa out. So far so good. Have a couple greens that have some minor poa, maybe 5%. No problems to speak of other than the Penn Cross gets grainy from time to time. As for specs, I am unaware of specs. Let your mind wander.
