I played a local course once (and once only) that had Common Bermuda fairways, roughs, putting greens, tees. Basically the entire property where ever there weren't trees was wall-to-wall Common Bermuda interspersed with a fair crop of weeds. The putting greens as far as I can recall were basically round areas with one sprinkler head in the middle so the "green" was the lusher Bermuda grass within the throw of that sprinkler. Otherwise, the (unirrigated) fairways and roughs were almost indistinguishable and it wasn't that easy to tell putting green from fairway since there had been some rain recently. I think they mowed the greens every couple of days, the fairway every couple of weeks and the rough a couple of times per summer. Worst 15 dollars I ever wasted on a supposed round of golf.
Now I suppose from some perspectives (M.H.M.? J.V.G?) I should accept that the course must be played as I find it. There was grass to putt on, longer grass to play approach shots from, flattish areas from which to tee off, longer unkempt grass to disappear a mishit tee ball. It's golf! What am I complaining about?
But complain I did. Common Bermuda may make a dandy rough and if kept short, de-thatched and de-weeded can even make an acceptable fairway. Putting green? Not so much. Putting green Stimping around 2.5-3 feet? Not a chance, I'd rather spend the afternoon at work in a staff meeting.
I think Jud is sharing the opinion that ankle-deep Paspalum bordering greens is akin to 3/8" Common Bermuda for a putting surface. Sure it's supposed to be a hazard but almost anything or nothing at all would make a more suitable greenside hazard.
