|: The 6' is just a flat ramp, 60 degree slope so its not vert (90) like the halfpipe. So its easy for me. Looking straight down gets to me still lol.
So the 5' ramp is vert? Keep off of it. The geometry is wrong, it is just plain dangerous. A 5' vert ramp is too steep. You can hurt yourself really bad in such a contraption.
