Is Twitch a Good Champion to Main/Soloq?
Trying a regimen of champion maining through SummonerSchool, and chose 3 champs for each of my two main roles for the purpose of getting better in ranked.
Champs for ADC:
Champs for Jungle:

I chose them because I liked their personalities/characters and not on the basis of whether or not I could carry with them, as was stipulated by the guideline for choosing champions to main in the regimen. So far not having much success with Twitch/Jinx. Any assistance with how I should be playing each? (Also putting in mind that general questions lead to bland general answers).
EDIT: So the general gist I'm getting from this post is that Twitch and Jinx are poor choices for me. On the one hand I don't want to abandon them entirely, but on the other hand I AM getting burned out on losing/AFKing with them. Tristana, I have loads more experience with. Other problem I'm having is that I feel like I'm obligated to stick with Twitch and Jinx, since I've indicated them as my ADC roster and I'm supposed to play only them and the other four in Ranked for the next 30 days. Not that it's wholly binding, but I'm at a loss as to who I should go with next. I don't know who I lean more towards, since habitually I'm the kind of person who tends to give up after getting burned out.
