Need some feedback from some ADC mains on about supports.

Personally I'm a terrible ADC that can either do good or right out feed my arse off. But I do run pretty good solid support runs to the point ADC mains have friend requested me for ranked to duo with to climb elo. So I really enjoy playing the support role and off meta supports. Like I've been finding success playing Ahri with Jihn and MF ADC. Experimenting with support choices can be a pain since I don't always get someone that plays the ADC I'm looking for to with an off-meta pick. I've decided to ask you guys on your feedback on the best support champs you've experienced.

I ask you guys on what you feel on what is the best supports for you with your ADC choices. Include normal and off-meta supports. Thank you.
