I typically only run long esters of Test.
However, I only run Tren Ace. I don't fuck with Tren E. If shit hits the fan, it takes too long to bail out where with Ace, I can just stop pinning it and it will be out of my system in a few days vs. a few weeks.
Also Ace kicks in faster and you don't have to pin as much to get the same effect as you do with Tren E because of the ester weights.
So I would recommened Test E or C if you want a longer ester and always Tren A if you want to run Tren.
Just my two cents.
