Flex fuel vs 2 tune 93/e50

So, im getting ready to install my FI stage 2 hpfp, flowmax + v2.5, and a dorche flex fuel kit. Im sorta torn between going with two individual tunes, a 93 tune, and a e40/e50 tune(whichever will produce the best power imo). Or going full flex fuel. Ive been doing some reading, and it seems that a dedicated e40/50 tune is going to provide noteably better power. Is this the case? would be an easy no brainer for me to just run a e40 tune, as i already do this now. So nothing would really change. However, i like the idea of running a flex fuel setup so i can not have to be as precise in my fuel mixing, but i hate the idea of kneecapping myself. Im planning on going with odin tuned for a tuner, so ive got options. Thoughts/opinions?
