Yes, it was my first Tren experience at 400, I ran tren-a at 700 which is about 1g of Tren-e with ester weights
It's silly to compare esters like that; but just to be accurate, the difference between acetate and enanthate is 13% per weight - so it would (theoretically speaking) be more like 805mg.
I'll take physical over mental any day. At least you can treat physical sides; no dice for mental other than trying to ignore them. But everyone's different.
You have a few options.
1. You can run both esters from day 1 and cease the ace at week 4, then bring it back once you run out of enanthate.
2. Start with just the enanthate and finish with the acetate.
3. Put the enanthate away for now, or sell it to someone that prefers long esters - and pick up more acetate.
4. Do the opposite of 3, and run a longer enanthate cycle. This way you get an opportunity to see which ester you prefer.
I'm not a huge fan of really short cycles, but those are the "safest" options I can think of. If you know you can handle sides, a long ester at much higher doses will actually give you more bang for your buck - even in a shorter time frame. You just have to increase them substantially, which I'm personally too afraid of doing as tren starts to wreck me at 800mg+/wk.

Edit: Darkwing86 actually has a good point. It also matters how much of each you have. Good call!
