I'm right there with you, I can manufacture some but like I mentioned before where I play there are a lot of forced carries and if you don't carry and are short the ball usually don't run, unless its a skulled wedge / thin bullet. No rough can stop those.
90% of my rounds i break 80 but only 40% of them are dbogey free so i definitly vote for DB Free is harder.
At the moment is what im working at, 0 OB, water and double bogey. A lot of shot zones analisis in progress off the tee.
