Replying to Summer setup is being weird help

finally got to sesh my summer setup and it wasn't very fun. frustrating and disappointing we're the only ways to describe it, but it wasn't because i didn't have enough speed (although i'm gonna try to get more), it's the rail i think. it's a 6" 14' SDR 35 pvc pipe that should be perfect and it's angled flat/very slightly down. there were a few times were i would straight up just stop dead before the end of the rail and then slide off. it took an aggressive drop in and a LOT of scissoring to make it the end and even then i wouldn't be able to blind 2 if i were jackson karsteter. i used a watering can to get dish soap and water on it like 5 times. i would think that even at like 1 mph i should be able to make it to the end, at least that works during the winter. anyways help me
