I don't think there would be a need for the Tbol, EQ will keep working long term and as long as you r diet and training is good, you should be able to keep making progress until the end. The best time to run orals is when you start your cycle, as you ahve set up with the dbol. After that, you should be golden.
As for the adex, I dont see a problem using a low dose, as you outlined, to keep estrogen lower, while getting through PCT, An AI will give anyone a better test to estrogen ratio, on or off cycle
