Yeah I have heard the same thing, basically due to the fact that the accumulated amount of tren in the body is going to be much higher than if you did 100mg ed. I've heard most doing 200-500mg Ethn wk. If you do Ethn its really 50/50 shot, either you get the right dose or the wrong dose. You could also do EOD shots with the Ace. ED shots are easier to deal with if you use a 25g pin. I ususally only use a 23g, but when I do ED I swap it up with 23g for the quads and glutes and the 25 for sholder or tricep and sometimes the quads.
If money is not a concern you try to avoid any gyno from tren by taking Dostinex, but if I remember correctly it can be expensive. I think that is mainly due to the fact that the amounts sold are like a bulk size. There is also a generic version, of sort, but I don't remember what it is called.
