e5 doesn't make sense to me .. it is just setting up a target for the dark squared bishop! (that's not to say it is bad per se I just think it would take more theory to learn the theory, something I'm not willing to do for an opening that i would see maybe once every 2 years)
d5 makes a bit more sense but i still think Nf6 followed by e6 is simple and effective .. with the added bonus of only having to remember 2 moves .. the rest of the opening plays itself
