ok well i finnal built my self a roll in and a box, the roll in is 4.5feet high and 4X4 on the top, and 4x8 for the down slope, and the box is about 2 feet high and 12 feet long.
k so the problem i have is im going to fast and even if i try to slow my self down with my polls, or do a pizza on the way down i still go too fast, so all i want is just some ideas of what i can do to slow myself down. I also thought of makeing my box a bit of an up box (by a few degrees) but im not sure if that is the best solution.
