One aim of manufacturers should be to ensure that every rider of a particular model has the same "rider experience". Imagine you on your 26" MTB and a 5'3" rider on the very smallest of the same model. Will you have the same experience? The smaller rider is much higher off the ground relative to their height, with a longer bike and their weight is further forward.

The rider centre of gravity is more dependant on bottom bracket height than hub height, and BB height is constant throughout the size range so the bigger you get, the lower you ride.

Putting the largest rider on 29" gives them a feel similar to med rider on med 26" MTB. If you dont like that feel, just sympathize with what MTBers have had to endure for the last 30 yrs. Bring on the 24er for med guys.
