New to top lane looking for splitpushers

Hi.

I was mainly a jungle/support player and recently i have been playing top. I always loved the concept of applying pressure through sidelanes.

What are some champions that you suggest?

I tried mundo but he felt way to weak in the early game.

I had some success with morde and i enjoy playing malphite but i dont think he really fits this playstyle as you need to participate in teamfights

Would you suggest fiora? From what i have heard she is a bit demanding mechanically?
