It's pretty obvious that people of large build wont be using the same wheels as the average build people. Indeed the bigger you are the more you need grip because the centrifugal force drags you to the outside when entering a corner. Thus the bigger you are the more the centrifugal force affects you and so the more you need grip to pop of the corner and generate more speed.

The only way to get more grip is to use the SNAP of the wheel: the bend of the wheels when pushing on them. This will provide you the required grip. There are various ways of getting more bend. You can use a softer hub or a softer tire.

MPC turbo wheels, with the new thicker MTECH ring pops more. Larger and heavier people will probably be using the BTT 5 or the RWT 5 and the average weight people the RWT 8 and BTT 8. MPC is the only brand to offer wheels with two different durometers of the inner ring to make sure every skater can get the right wheels!!!

Many skaters think: " more weight means bigger footprint and more boggy roll hence why i choose XXF over XF ". This is not correct.

"A heavier skater causes the wheel to make a larger foot print and this will increase rolling resistance and make you slow, therefore you need harder wheels to have a minimal foot print and go faster." A larger foot print does not always result in more roll resistance. Resistance is a product of force times coefficient of friction. Its independent of the foot print area. In cycling for example, there is a trend of using wider tires.

Guess this would only make sense when you just roll and not push!
When you want to go fast, you need to push, for which you need grip.

Indeed technically heavy people should increase the footprint when standing on the wheel but actually it does not affect the roll. Because you generate more speed while pushing than rolling. The larger foot print isn't an issue. If you want to generate more speed you need more traction for a higher push efficiency.
