My back feeble to back smith and banger (Switch laser flip) seem to be the favorites of most people.
It had taken me...about 3 hours to do. I got it about 4 times prior, but none the looked as good and kept the same speed. I also had AI skaters constantly trying to skate the rail and get in my way, it got so annoying that I had to do delete the dude off my friends list because his AI kept getting in the way.
Also, my one foot tail tap over the roll-in at the Snake Run park. My tail tap at 2:11. The tailside kickflip out at 2:51 and the blunt kickflip out after it.
