In his Nothing But The Truth part above, the line at 0:15 looks like he should lose control with just about every movement, but Omar handles the speed and flies on by with a couple of fun, fast tricks, following them with a beautifully stomped switch heel without slowing. Seeing his shirt flying around at 0:55 gives you a reasonable idea of just how fast he is going, uphill nonetheless. Really, this whole part is filled with some very fast skating, and Omar's controlled-chaotic style is what makes him stand out as a super fast skater.
In Mind Field, Omar snakes around a sweet channel at about 1:08 to show off his control at such high speeds. Obviously there are tons of speedy clips throughout the whole part but this one in particular sticks out.
Looking at Omar's part in First Love, there's not much need to go further than the introductory hill bomb at 0:36. The way he shows no problems at all with the speed and even has enough confident control to woosh around with his scraping ollies just for fun is remarkable. Also, in the line at 3:08, he hits a ledge with a back tail at probably the highest speed I've seen someone somewhat swerve into the ledge. Then the last 4 clips are all just full-on fast assaults of the spots, including some sweet downhill action.
In this Spitfire commercial at 0:43 Omar hits the top ledge on a bank fast enough that he doesn't even need to get on top of the smith grind to cover more than half of the ledge, all before gliding through a few more pushes (exaggerating how slow the crowd is skating) towards a huge ollie. And the clip right after that with the gap to 50-50 all the way through is a true testament to how fast he skates.
