i have a kx80 and i want to jump nicely. however my dad says that when i have a short take off the front compresses than uncompresses while the rear compresses. he said it will be very hard to land this way. so what type of jumps are better?, short steep ones? or a longer face? so the bike can be uncomressed in the front and back. i dont really know a whole lot about jumping. but i know it is heck of fun. thanx
