After reading and talking to people in the Finance Industry, it makes sense to trade with IEX. Why would you not?
Don't you want to see your trades hit the second you request it, as opposed to the extra second delay in the other exchanges.... This is a NO BRAINER...The ones who oppose this are the ones probably getting some sort of kickback from the other exchanges.

Best of luck to you
