Pupster has a huge area to mow and he found what works for him,on large properties I have found it works for me too.

I am not going back to a 10 or 12 MPH Z after running a faster unit. It all depends on weather you can get away with it for your conditions.

The Pupster means no harm he is just excited about his new toy.
A 72 will not have a faster blade tip speed than a 60 if all things are equal. I've repeated this to you many times. A 72s blade is about 2 inches longer on each end than a 60s blades. Therefore it must treble further to make one rotation. Let me give you the simplest example I can. Two race cars are running exactly the same speed at Daytona one car(60) is hugging the inside line, the other (72) is running next to the wall. Which one will finish their lap first? Ding ding ding the 60 will because its total distance is a little shorter than the distance the 72 covers.
