What should I main.

My best role in League is jungler but I often find that I don't have as much as an impact as I would if I were in lane. But, then again, when I do go in lane, someone who doesn't know how to jungle decides to screw up the entire game. Should I keep trying to improve my jungle so that I can carry a game or should I main a solo lane in season 4 to climb elo? My best champ is and I rarely screw up in the jungle. He has good cc, and I know J4 inside out. Can you guys give me some carry junglers and tips to carrying?
