Dropping the test dose, that would depend on the goal of the cycle. Saying because you're using Tren you need a low test dose doesn't make sense to me if you're saying in the basis that it has to be done this way. During all my years of contest prep I cannot think of one time where my test dose was lower than my Tren dose through the brunt of the cycle with the exception being at the very end of the diet. As for off-season, test would always be higher.
Last thing, caber or prami....Tren can easily be used without these. I know a lot of guys here preach the prolactin/gyno speech but I disagree. Will it hurt? No. Is it a must? No.
