It's hard to pick a worst or best hole at Pine Valley. To answer this threads question, I do not think #10 is the worst hole. I think it is a very demanding short par 3. The green is just brutal to most hole locations. I think it plays the most difficult when the green is softer because I find it tough controlling the spin on the tee shot with the slope in that green.
I find the 12th to be the easiest on the course by a fairly wide margin, but I don't think because it is easier, it's also the worst hole either.
