I play both roles relatively comfortably.
Only around 1250~ Elo. Gotta' love those throwers. :P
My main Junglers are Maokai, Cho'Gath, Lee sin, Amumu. (Also doing a lot of theory crafting with multiple different bruiser and support junglers, just bought quite a few with my most recent RP purchase.)
Main ADcs: Ezreal, Corki, Caitlyn. (Planning on playing others a lot more if I end up becoming main ADc such as Graves, Varus, Vayne.)
Still relatively new I suppose you could say. ~70ish Champions.
