I just heard back from MK.
"Jumping is made easier due to the weight reduction of the revolution blade. The revolution blades have also been designed to cushion the skater’s landings without affecting the amount of pressure required to take off for jumps. Also, you should not have to press harder to maintain the edges. If a skater has to press harder to maintain an edge, they might require a deeper grind on their blades.
Regarding the statement about the weight limit of the Revolution blades being 150 pounds, this is not true. You should have no concerns about the weight restrictions on this blade.
The screw holes in the Professional Revolution are different than the standard Professional because of the carbon fitting.
Our 6 week exchange scheme allows the skater to trial the revolution or parabolic blades. If during those six weeks you decide that the blade is not right for you, simply return to your dealer to exchange for a brand new traditional pair of blades."
