I've got to be honest, I'm a little surprised, I thought most of the guys here were anti stripes...
David,
I'm sure it doesn't suit all properties, but in my clubs case we have long narrow fairways. With long narrow fairways, this means more stripes, more picking up the reels and turning in the rough. When you mow the 50/50 cut, more time is spent reels down mowing, and less picking up reels and turning. Not to mention the wear and tear in the rough. So, in my clubs case it definitely saves time which would also equal less diesel.
