Replying to Atv tow in jumps

I am stoked for this winter and i was thinkin about buildin a kick ass backyard setup, better than i ever did before.....my dad has a tractor which he lets me use to clear the driveway when it snows, so snow is definitly not a problem.....i was thinkin about makin a 30-35 footer with an atv tow in, now i know its goona be hard to explain but i will try to get some pics up once winter comes but if you have ever built a jump with a tow in is there any tips to buildin it/ how much speed would i need for it,
