I have no Bermuda other than some invasive common Bermuda in my tall turf fescue.. The contour mower's max cut height is only about 3 1/3" and that is really too short for turf type fascue. When cutting shorter varieties of grass the countour shines, it is a golf course mower, although not a greens mower. The 72" cuts my grass better than did the contour, and I typically use it at the 5" setting or one to two notches down, quite tall. My judgement is that the conour is better for short grass and the newer design 72 is better for taller cutting.
