Replying to Sencia Park; Home made park

Ehhh people what up, im just gonna cut to the chase.. next winter im making my own park. I own 140 acres and have two hills that im planning on building on. The first (pics to follow shortly) is about 200M in vertical and the second is closer to 300M. On the 300M i clear cut a trail through a tree line for the rope tow which is installed (pics to follow) i didn't buy it from a ski club or anything all it is is an old chevy motor that moves the cable.
The plan is for a jump line on to be on the 200M hill even though its smaller. The catch is its a hell of a lot steeper = more speed. It would also just be serviced by someone on a snowmobile towing people to the top.
The 300M hill is a designated jibbing zone with the exception of a 15M kicker to a natural hill landing.
What i need for you newschoolers, are suggestions. Currently i only have 4 rails made for jibbing zone. A 27ft down flat down, 17ft round bar, 21 foot battleship and a 30ft round bar. Im in the midst of making a box but i dont want to make too many because of cost. If there are any cool features you think i should make hit me up.
