Many, Many of the top clubs mow angles on their fairways and try to burn in the stripes. Many for PGA Tour events, also. Think of the pictures we have all see of Pine Valley, Oakmont, Pebble Beach, Kinloch, Peachtree, Sahalee, Cherry Hills, RTJ International, Mountain Top, Wade Hampton, Sage Valley, Harbor Town, Bay Hill, Dove Mountain, TPC Scottsdale, Firestone, They stripe fairways, no big deal and most of golfing american enjoys it and as long as the other cultural practices of verticutting and topdressing are in place, it's not bad for the plant. Personally, I am a big fan of the side to side stripe and it leave no lines when looking from the tee. In fact, we're going to mow that way this morning for opeing day, as the 1/2 and 1/2 look doesnt save much time with our fairways.
