Replying to PLEASE TAKE A LOOK THANKS

ok so right now i have a 6 foot straight pvc rail (double barrel)  its alot of fun but ur on it for like a total of 2 seconds so like no time to do anything its pretty tall so i just bought some lumber and pvc
i have the thought of making a 10ft up rail that would lead up to the 6ft or even a down what should i do ns i have:
1x 6ft straight rail prob 2ft tall (kinda tall)
1x 10ft 2x4
2x 8ft 2x4
3x pvc 10ft (enough to fit on the 2x4 as a shotgun style

i was thinking of doing this more or less of a shorter down tho
