flex choice help

flame or codysun as my flex?

I chose flame because imt has a favorable solo lane including top/jung/mid and nobody is certain how their botlane will perform. another part is the fact that they play against tsm this week, and since its wildturtle and he is known for being a very aggressive adc I feel that flame would be a better choice,

my adc is wildturtle and my top is expect if you were wondering...
