My next champion buy

So, I play mostly top/jg, and was wanting some opinions on my next champ to buy. I do well with trundle, something like a 70% win rate with him in my ranked games(and horrible rate [not about 50%] with any one else). Who are some other good top laners? I have yorick and darius as well, and like them both enough but they dont click with me the same way trundle did. Though i immensely enjoy yorick
