Airwalks & Double body flips

For Airwalks you need to do a nose or tail grab and then press the no-foot button (B on Xbox controllers). For double flips, they're hard but not impossible. I do find that trying to do 900s way more difficult than it should be, the amount of speed and air you need to make it possible is beyond rediculous and might as well be Tony Hawks Pro Skater for the amount of air you have to get to make it work. I also find that compared to skate 3 the flip system is a lot less responsive and makes doing something like a McTwist or a BS Rodeo much more of a pain in the butt to get to rotate right.
