So I have pretty much an unlimited budge, and unlimited resources (as in I have access to any tools). Me and a few friends cleared out a flat peice of land in the woods behind my house and we are looking to build a setup we can use all year around. What I want to build is a 5 foot by 10 foot drop in (size can vary depending on the type of replies I get). I haven't even started to think about the rail yet. I drew a basic side view of what I want:
Now, I'm worried about two things:
1) Will I get enough speed? The downslope is only 3ft. And there is 3 ft of flat after it
2) Is 3ft of flat enough? Should it be more?
