Rythym section, I'll try and explain it a bit better,
1st two jumps 4ft up ramp and down ramp 1ft high, 2nd pair 4ft up ramp 8ft down ramp 2ft high, final pair 4ft up ramp and down ramp at 1ft high.
It'll have smooth transitions between each set not just two bits of mdf pushed together like this \/, using thin boards that bend.
