Good Top lane champs to main?

...I just typed this out only for it to disappear on me. -salt-

I'm a support main who just got out of Bronze, and as much I want to keep my dream alive of climbing the ranks (albeit very very slowly) as a solo support I figured I should have a secondary role too, juuuust incase my dream gets crushed ;n;.

My particular fear is if I'm first pick top lane, what's a safe pick for then?

These are my top three support champions if it helps any

In the limited cases where I have gone top lane I've found I most enjoy playing a tank top, ( <typically these two) where even if I lose lane I can just farm and be somewhat useful in teamfights via cc. But I know that doesn't always work and there are other playstyles.

On a side note, is building or even on a tank top a bad idea? I often feel vulnerable top lane because of lack of vision, and often wonder if its worth getting a sightstone so then we could have vision both top and bot side earlier on.

Thanks in advance! :D
