There is nothing wrong with mixing esters, though I would personally run it with either prop or suspension.
If you want to run a longer ester test, like the Enan ... then rather change your cycle up as follows:
Week 1-10: TestE at 250mg/week
Week 3-10: TrenA at 50mg EOD initially. If you can cope with the sides, then up the dosage to 75mg EOD.
Have your caber on hand for the Tren, even though it is a short ester and also have Aromasin or Adex on hand for Test sides, even though the dosage there is quite low.
