So i know this should be in the build 101 cult, but im trying to finish it today and i know ill get a quicker response here. Im building this set-up for summer and winter, whole thing is going to be turfed, and its going to have this nylon lattice stuff across the first few feet at the steepest part. each sheet of plywood is 2feet long, rail is 13 ft long and on a slight incline. Will i have enough speed as is? Any other suggestions would be appriciated. Thanks.
