Riven build

I played Riven a lot in the past and I would like to get back into playing her. I had a long spat as a GP one trick (for the most part) just like good 'ol Tobias Fate, but I got bored of it.

I basically am wondering what the most effective build would be on her. Another thing I was wondering was if Triforce would be a good item to build on her. In my head it seems like it could be solid with the sheen procs, however I don't really feel like going into a game and being flamed for building weird on top of the inevitable flaming I'll receive for playing Riven in the first place.

Thanks!__
