Nice choices! A friend of mine demod the contour mower,it's really a golf,course suited mower,something to keep the turf manicured,not take down a weeks growth in the spring,they don't mow well when the grass gets tall at all,if you let your grass get tall before mowing,you won't like that mower,you'd be better off with the 6ft straight deck,it devours tall grass for breakfast...
